Bugs

1) Disease that lowers health by -1 broken. Only health maximum affected, units had 21/20 health.

2) Forest/river tiles never have essence, Tile yields always low there, even when they are next to 2 resources. Why?

3) Deadly quest with demon Kainen in his tower broken. When he dies you get like 20exp and its just over, no message or rewards.

4) Blessed hammer is offered as a reward for deadly quest when you cleanse a tomb. It is a low level item though and found in some beginner lairs. An angelic longsword would be a more fitting reward.

5) In tactical combat the AI ignores resistances. Had cindercorpses casting their fire spell on the only troop I had with fire resistance.

6) AI does not select vulnerable targets if its already touching another unit.

7) Lv requirements on some items too high. Ignys axe is lv 15 and Druss lade lv 18. Ive never gotten a lv 15 hero when playing on a medium map, I conquer the entire map before reaching lv15.

8) AI killed all the monsters in the Imperium but didn't build a city there. Instead kept sending pioneers into my base to build on top of an air shard. Also Imperium is only a 4/4 tile and when you conquer it there is no message or reward.

9) Temple of essence says in its description that it gives -10 unrest per essence. However my city with 4 essence only got -15 from it. Maybe its only -5 per essence and it didn't update when I got oracle?

10) Imperium river either never counted as a river or turns into plains(still looks like a river) when Imperium city built. Fog of war has weird affect on Imperium walls, they disappear and reappear.

11) Pyre of man gives mediocre experience and mediocre land for completing wildland. Oh ya and a rusty gauntlet. On completion wildland looks stupid as plains has a bunch of magma rocks sticking out in weird spots.

12) Prismatic potion causes weird stuff to happen if you use it than auto calc. Renders you invincible permanently it seems but is plagued by bugs, like some battles ending with only half the enemies dead and you still alive. 

Balance

1) Player needs access to a more diverse set of items. Either through quests giving more choices, some kind of artifact merchant or whatever. It seems like most games I always get the same ice spears, shadow daggers and blessed hammers. I keep hearing about all these rare artifacts but never see them.

2) Too many horses and wargs. It seems like very city has a horse and a warg place, In three games ive played Ive never had a shortage. In one game every unit I ever built was mounted, must have spent over a thousand horses.

3) Plague Event seems unbalanced. Cure plague is way to expensive considering you get exp for paying 50 gildar and a fun quest. It seems like they thought giving the player easy to kill enemies and a quest was somehow a bad thing?

4) Mid to late game champions seem very weak and useless. They really lack in basic traits like  spellmastery and lethal. They seem not only all around weak but all gimmick and no substance.

5) Elite units are too cheap. In a good fortress I easily produce a three trait mounted unit in full chainmail and with 2 artifacts in 1 turn. All those tiny production costs don't mean anything. Why build anything but mounted super troopers if you can do it in one turn from a super fortress that produces them at lv 5 with endurance and +20 accuracy. AI cant match this.

6) Swords/hammers seem a little underpowered. Counterstrike and bash is nice but not a match for the skills cleave or impale. Adding 25% counterstrike damage is especially not as good as 25% cleave bonus. All the weapon Master traits could use some love.

7) Rush is OP. Lets me cross the map and take out any target before they can cast or shoot. Also lets me set up brutal cleaves before enemy can move.

8) Damage on late game weapons and def on plate-mail is too high. Impossible to stop plate-mail units with anything but mauls or pikes. Doesn't matter if unit is encumbered becuase its a laughable -2/4 initiative penalty for like 30 def.

9) Encumbrance should be a % loss and affect dodge to stop quick heroes from just ignoring encumbrance penalties.

10) Pyre of Man is a terrible terrible caster in both terms of AI and stats. His fireball was thrown at a single wisp and failed to kill it, only dealing like half damage to it.

11) Counterstrike doesn't work on abilities like impale, doublestrike and cleave. Severely reducing the utility of counterstrike. For the sake of balance units should counter when targeted by skills.

12) Hurl Boulder is UP. Misses like 90% of the time and never does more than single digit damage. It really only makes it much easier to kill units that have it. Should probably be tied to units attack or something.
