Coal starts off at a ridiculously low drop rate. focus on bringing up luck and it starts to feel like you are swinging a pickax in a mine rather than a sword.
not that the nerfs weren't necessary, but you wield the nerf bat like like Mike Meyers wields a machete. Viciously, gutting the dropoff in mana cost and usefulness of my armor. ...actually makes it more fun, though.
it seems if you resurrect using a glyph while fighting the spirits (the ones that will join you if you win) you do not have a chance to fight them again and nor can you go through the space that it occupies
Found a bug/feature if on a hunt you dominate an enemy at the end of the battle, you can keep that enemy for future battles. I have a few spiders and a wolf in my army now. pretty cool. it says that they are regular troops, but I also have 53/50 people in my army
The most fun I had was messing around after killing the dragon. After the dragon is dead I'd like to see a few more options. For instance, it'd be fun to be able to buy a randomize floor. the lower the floor the more expensive. Or, even a randomize tile. another thing that'd be fun is a +death buy button adding more traps and monsters to a floor (which is especially necessary for the upper levels after killing the dragon. there are not enough monsters for all the level 0 heroes.)
all you need are poison towers really... I ended the game with 5 ice towers 4 poison towers and 3 or 4 ultimates and I didn't lose a life... the game is too easy. as for hitting fast mobs, poison + water gets the job done.
