1. Allow items to demand prerequisites from unitstats. Items can already require user level. I would like the possibility of making an item only useable if you have a certain unitstat, let's say strength, above a certain limit. Ideally, it would use the current prereq modifier, but instead of only accepting unitlevel it would also accept any unitstat.

        <Prereq>
            <Type>UnitStat_ThisIsMyNewUnitStat</Type>
            <Attribute>5</Attribute>
        </Prereq>

This would also need reflecting in the UI, the item should be unequippable unless the current hero has the right stats. Hovering over an unequippable item should tell the user what stat is needed, and what amount of it is needed.

The purpose of such a tag can be making certain items, like magic items, require a certain skill-level in unitstats before it can be equipped. For example a tome teaching a character a new spell level might require a very high intelligence. Or Thor, the god of thunder, may be the only one who can lift his hammer since only he is UnitStat_Worthy.

2. MeleeAppliesSpell is a trigger used to automatically apply things to a target when the unit owner hits it in melee. Currently, the trigger can only affect whoever is the target, and the target only. I would like spells cast with this trigger to respect the <ApplyToCaster> tag found inside modifiers. For example, I should be able to have a modifier that says "every time this unit strikes an enemy in melee, this unit gains 1 hitpoint". (implemented)

3. The spell "chaos" allows us some limited access to randomness in spells. I would like to increase how we can actually use this. Currently, it functions by having the tag <AppliesRandomModifier>1</AppliesRandomModifier> in the spelldef, and it then randomly chooses any one of the modifiers in the spell. I want to expand on this, by introducing one of two possible additional tags. The purpose of both of these tags is to limit what modifiers get chosen, and what modifiers ALWAYS happen no matter what modifier gets chosen.

A new tag that says "This Always Happens" in a spell with <AppliesRandomModifier>. In the below quote, the first modifier should always happen, and the game should randomly choose between the other two.

In other words the spell should do either 12+12 cold damage, or 12+6 damage. This kind of tag would GREATLY expand on the possible uses of randomness in spells.

@Werewindlefr It would be useful to have different triggers for dodged melee attack, and dodged ranged attack. I would also like a similar trigger to when a spell gets resisted. It should enable a user to have a trait like - "If this unit resists a spell or magical ability, this unit gains 10 hitpoints".

Another request. I would very much like the unit design trait window to support mutually exclusive traits.

Currently, we can implement mutually exclusive traits and it functions as expected (they get only one bonus from the last clicked), but the UI does not show it so. Currently, when I select such a trait, I can still select the others (but only one is actually applied to the unit). The problem is that the UI is very messy - it looks like both are selected.

My request is that when I select a mutually exclusive trait, any other mutually exclusive trait from the same AbilityBonus group should automatically be de-selected. In addition, the AI would have to follow the same rules, and not bug out while designing such units. In other words, selecting one mutually exclusive trait should rule out selecting any other from the same group when the AI randomly assigns traits.

Here is an example of two traits that should be mutually exclusive: http://pastebin.com/raw.php?i=ixv5Q083

And here is what it currently looks like when I select both: http://i.imgur.com/mgPK0.jpg

I think the way to do this would be to have a tag called something like <ApplyToTarget>, and have that gamemodifier call another spell with a radius.

Please. No. Prerequisite are bad, bad, bad. Even level prerequisite are bad. Just give penalties due to the lack of a specific stat. For instance if you need 12 str and you have 10 then you just apply 80% of the effect of the item. Or something like that.

Give Quests a prereq function like buildings have. 

Allow a tech to spawn new goodie huts like we had in WoM. 

I'm going to place this thread here in hopes one of the Devs will see it or one of you fine Modders of note can pass it along. Having done a number of spells in EWOM and now messing with FE I can see a number of items I think we need or need adjusted to really make the magic system come alive in the game either through the Devs or the Mod community. I'm not going to debate manna pools or rates but actual code/mechanics to take this and crank it up a level. So here I go.

1. Mana Shield. Dump it. In its place add a unitstat for Magic HP (call it what you want). This stat would take damage first if there are points in it before the characters hit points. I'd add it to everyone including creatures. With that we can make shiled spells that have more detail and control over cost, points in the shield, holding costs, etc. Along with this stat having attributes for Weak (increase the damage by a percentage of the attack type, fire, piercing, etc), Strong (reduce the incoming damage by a percentage of the type), Reflect (percentage of the damage goes back to the attacker), and  Resistance (casters value to defend against negation spells). I'm sure there are a few other attributes like color and FX. This would allow for a number of spells and abilities to match up with the now various types of damage and really be a cool game mechanic.

2. Summon Item. There really needs to be a way to "summon" not just give (I can do that now) an item. This allows for spells where the caster can say for example, summon a Firesteed to ride. Costs mana to cast, mana to hold, and can be dispelled when the caster does not need it. Right now GiveItem does the first two items, but it can't dispell and remove the item. There are a number of cool ideas here with mounts, weapons, and armor that could be made.

3. A MultipleCast Attribute. We need to have the ability to make spells in which more then one target can be engaged (but not area effect) or hit a single target with multiple shots. I'm looking at the classical fantasy missiles spells were the caster can fire off a number of low damage (or high) attacks from the single cast. The new damage types makes FE a great system for all sorts of missile and even hand to hand attack spells. Ice daggers, rocks, arrows, fire darts, lightning fist, etc. Again the game can get a vast number of cool new spells.

4. A second for an AllwaysTriggers Tag. We need it for spells/weapons/items so a Gamemodifier block will do its thing if there is a random effect or other logical triggers in play.

I agree with this.

I'd like to see SpellResourceCost moved into a tag within GameModifiers, rather than the current implementation.

Specifically, I would want to be able to alter mana costs as a spell grew more powerful, usually through number of shards.

I forgot to mention it, but it would be great if <AppliesRandomModifier>1</AppliesRandomModifier> would apply on strategic map as well.

(implemented)

Another request, if I have a unittype in the tech tree that becomes unlocked when I research a tech, I would very much like for that unittype to be clickable in the tech tree list in the bottom right. When clicked, the hiergamenon should open and show the relevant entry for the unittype.

In other words, I want to make clicking this

bring me to this

When you create a custom race there doesn't appear to be any way to provide custom factions based off that race with a certain building style, spellbook, or other things without editing xml. This appears to happen automatically with the ingame races. I would like to be able to add tags to custom races that determine the spellbook, buildingstyle, wallstyle, and cityhubs of factions based off that race. Having to manually edit each faction based off that race is annoying.
