I think precision and true strike are either both useful or both useless, because they increase the chance of hitting the target.

Assassins are all about accuracy. It is their main stat. Critical is their secondary. A guaranteed hit is an excellent counter to many spells and units with a very high dodge. Unfortunately, accuracy goes up with every level where dodge does not. This is making Assassins useless.

Yep and thats the reason why i think precision and true strike are useless at higher levels.

Vital Strike should increase the critical hit chance by 5, 10 and 15 % instead of increasing the critical hit chance and the critical damage.

I would agree with your analysis.  I'm happy to hire a hero with this trait, but I have not seen enough benefit to spend a level up on it.

I too never choose Gambler's Strike, but I did find a champ who had it already in one game. It wasn't bugged in the sense that it caused a crash, but I never saw it achieve more than normal damage. Gambler's strike first turn = 8 dmg, normal attack second turn = 8 dmg. I had similar results the other half-dozen times I used it.

One general thing that I will say about the traits is that, as implemented, Discipline (+1 str/lvl) and Brilliance (+1 int/lvl) are OP to the point that I always choose the Warrior path or Mage path (whenever latent spellcasting ability is present) for all of my champs. I've played Assassin, Governor, and Defender paths as well, but always as a secondary/tertiary choice at high level, or because the champs came with it when recruited.

Ya, constitution already scales with level inherently, 10 constitution at level 1 gives less hitpoints than it does at level 2.

The formula for hp bonus from constitution: (( UnitStat_Constitution * level * 0,3) + 3)

Then static bonuses are fine. Maybe Defender should get +6 Constitution, +2 Armor per 3 levels.

It may well be something that needs to be considered - scaling dodge with level (via dexterity), and scaling spell resistance with level.

After a bit of thought I have two main issues with the current level-up/trait system. 

Accuracy gained per level by every hero and traits granting bonuses to base attributes.

Starting with the latter, I feel that it would serve the game best to not allow heroes to gain or lose base attributes through level-up bonuses, traits, or injuries.  This would help mitigate effects like always choosing a certain attribute increase because it will positively effect X number of combat stats so it's always the best choice scenarios.  With balanced mana costs, attribute affecting spells are fine but alternatives like affecting combat stats should always be explored first if possible.

That being said, I feel that the accuracy per level business for all hero classes is a bit off.  No other stat but HP is gained on a per level basis*, and level based Accuracy gain just seems to break the game from about the early-mid-game on, because Dodge is no match for Accuracy at this point.  Maybe something like

Path of the Assassin: +1 Acc per level

Path of the Defender: +1 Dod per level

Path of the Warrior: +1 Att per level

Path of the Magi: +1 Spell Power per level

should be implemented.  It seems like this might help to make other stats, especially Dodge in this case, more viable.  Then if they decided to flesh out the trait system a bit more, from Path of the Warrior could come

Path of the Ranger: +1 Acc per level (-current level), +1 sight

for instance.

*: Not sure if I like this "D&D HP system" or not.  I will think on it and perhaps post some ideas later.

I for one definitely like the current "DnD HP system" where HP increases per level (even if constitution does not increase).

as far as stat increases go ...

perhaps 3 basic combat paths

Theif, Soldier, and Mage

Theif can split into Assassin (accuracy) or Acrobat (dodge)

Soldier can split into Guardsman (Defense) or Warrior/Fighter(Attack)

Mage can split into  Wizard/Sorcerer (Magical Power) ... and Sage/Druid/Warlock (Magical Defense)

Theif skills specialize in critical attacks, and possibly an element of stealth (a skill like 'bounty hunter' for extra gold from kills/combat)

Soldier skills specialize in 'mundane' combat

Mage skills specialize in various things of magical importance (like spell ability, summon strength, channeling of magic, and production of magic)

-> maybe a theif can pick a few Acrobat levels and a few Assassin levels, but cannot pick levels from the Mage or Soldier classes.

Perhaps +1 accuracy per Assassin level and +1 dodge per Acrobat level.

That way, you could either go all Acc or all Dodge, or do a hybrid of the two (instead of making it a flat +1 every 2 levels, and allowing both at the same time).

I think this would be better. The question is if it is possible

(you can only cross-class within your path, and cannot take skills from other paths)

So instead of a level 8 Hero of the Assassin Path ... You could have an Assassin4, Acrobat4 Hero of the Thief Path, or an Assassin8 Hero of the Thief path, or an Acrobat Hero of the Thief path, etc.

as far as skills, you could either have all thief skills available by pure thief level, or you could have skills requiring (assassin5) or (assassin2 acrobat2) or (acrobat5)

->each time you level, if you have chosen a martial path, you can take a level in either subset of your martial path, and get the bonus for that subset only (ie +1 Acc or +1 Dodge)

and yes ... I agree that perhaps stats other than HP could upgrade with level (but slower than the bonuses that you get from your given path).

And you could have Thief skills that increase Attack, or Soldier skills that increase dodge, but it would not be a level based bonus, or at least not as powerful as the base (+1 stat) that you get when taking a 'class level'.

*Perhaps when the Champion is created the Path is already chosen, or you could choose the path as soon as you get them. Either way, I think the Path system could be an intrinsic part of the Champion/Sov, as opposed to something chosen at level X.

at least, that might have to be the case if each level you choose which bonus you will get.

Warrior Traits: 

Path of the Warrior: +6 Strength, +2 Dexterity.

There is a good opportunity to add a per level bonus to Paths. A +1 per 2 levels or +2 per 3 levels would give a better progression to heroes. That would free up later traits to give actual abilities, instead of incremental stat gains. I would also give every Path a special ability. For Warrior: Flurry: +2 to Initiative, -50% Accuracy.

Bloodthirsty: +25% vs damaged enemies.

A nice trait. It offers a bonus that adds some interesting choices to combat. This is a keeper. 

Crushing Blow: +50% Attack, lose all Dodge next round.

On paper this ability looks good. You trade Dodge on the next turn to get extra damage on this turn. The Problem is that 50% attack to one unit is not that useful compared to most other abilities and they don't have a trade off. The best abilities will scale with level as this one does with damage, but one would only use this if one is fighting units that either are too weak for their attacks to matter, or the hero has very little dodge to begin with. Given the number of abilities that a Warrior has, this one is quickly tossed aside in almost every case in favor of something better. It also means not getting to use any special attacks a weapon confers. Maul is infinitely better and will always be preferred. I might change this one to do double damage and take away Initiative for one round. That way you are choosing to quickly kill a powerful enemy, but are taken out of the fight until you recover. This could also be the source of a new trait for Assassins: Critical Strike: Guaranteed Crit with +50% Crit damage, lose all Dodge for next round. Since Dodge is primarily how an Assassin stays alive, it offers a better tactical choice. 

Discipline: +1 Strength per level. 

You can guess what I think of this one. Too much Strength in the late game. Lower it to +1 per 2 levels and make it part of a Path trait for Warriors. You should want to avoid making traits that are so good it is not a choice, but an imperative. You could make each spell free and I would still rather have Discipline. It's so much better than everything else. It is also important to make sure this kind of trait is mutually exclusive with any others that are similar. It's the only way to prevent unjustly created god units. That should take more than 20 levels to get to. 

Double Strike: Attack twice at -4 Accuracy. 

This is a good idea, but needs to be implemented better. -4 Accuracy only matters to low level units. If the design is to give an extra attack to high level units, make a trait that gives +2 Initiative. If this trait is supposed to offer the chance to attack twice with a high chance to miss, make the Accuracy a percentage reduction. -33% would make sense. That way you still have a decent chance to hit, but you would only use this on targets with low dodge. I assume that is the design.

Leadership I-III: +1,2,3 to Accuracy for all units in army.

This is not a good trait. Accuracy is currently set up to give high level units the ability to wreck any lower level units. I hope that changes as hp alone does this quite well. Accuracy is not important enough for just one point to make a difference. Even with +6 you are not going to do much more in the endgame, where this trait is generally chosen. Even then, units either have way more or way less than the enemy according to level. I also think that Warriors don't really fit as leaders. Even if you disregard that, this kind of trait only applies when the hero is the highest level unit in the army. That will not usually be the case due to low Intelligence and thus XP. I would suggest making a Path of the General for this type of bonus. And even then you would need to either change the Accuracy level bonus or make this a +1 per level for every unit in army trait. 

Rage: +5 to Strength and Dexterity when under 50% hp. 

I like this trait, but it doesn't fit the title. This trait speaks to survival instincts. Rage is something worked up inside the hero, causing an adrenaline rush and tapping into his animistic instincts during a battle. I think there is room for both. Renaming this one Flight or Fight would be more appropriate as it has to do with panic more than anger. I set up my rage to like this: Rage: +6 Initiative for 2 rounds, -25% to Dex, Str, Int after effect. That way rage is more like a frenzy of attacks that wears out the hero after the adrenaline subsides. I think there is room for both and would be fine with calling mine Barbarian's Rage, just want to present an alternative. 

Tactician: +1 to Initiative for all units in army.

Once again the question of whether or not these abilities are supposed to only work for the leader of the army. Warriors will rarely be the highest level unit. A Path of the General makes more sense for this trait. There is also alot of Initiative being thrown around. This should be a stat that is closely watched so as to avoid letting units to get too many attacks. High Initiative should be something earned over a very long game. Right now it is handed out too often. +1 Initiative is a huge boon. Total Initiative for a Path should not be overly high unless it is a specialization of a specific Path. For instance, it makes sense for Slayers and Barbarians to have alot, but Knights and Paladins would be much slower. That's how I would balance it anyways.

Overall this is the best Path simply due to the Strength bonuses. Strength needs balance. This Path needs to have more abilities. I have several that would be great here. I also think this is a great Path that should lead to several new Paths at later levels. There is alot of room to make interesting Paths and this seems like a good starting point. Some of these traits need to be made in a Path of the General that can focus on Intelligence and bonuses to the whole army. It doesn't work to have Warriors lead an army as that would prevent us from having good mages in the army as well.

Not sure if we can calculate in that tag. It is a simple <perlevel>1</perlevel> tag. You could ask HF. 

hmm.

Can the per level tag only take integers? A <perlevel>0.5<perlevel> might be nice
