I'm late to the party, but here we go. Imo i wasted my time with this map. Yes, it's hard and yes, i cheated. My first 3 playthroughs ended up dying at the first necromancer wave.
What i saw: Empower spell, either doesn't work or it's useless, because you need level 5 to get from +1armor +1dmg to +2armor +1dmg. At level 9 Empower i had +2armor +2dmg. Either you wanted the spell to be like that or you trolled me hard.
Ent spell, imo it takes extremely long to make a tree, that dies quickly and or he dies on his own.
The AOE spell, it's good when you get surrounded, but like Empower, the dmg doesn't scale. So long term, it sucks. Why? because the enemy minions, regenerate faster their HP.
Meteor spell, it's simply retarded imo. You teleport in the group of minions, then wait to cast a meteor and guess what? The meteor can kill you if you are low hp.
The other spells that uses mana ("spirit"), i didn't look at them, because i'm not fast on the clicks to cycle power tabs. But the idea, was nice.
Bugs: I didn't saw any boss, that you mentioned in Quest log. I searched and searched and really no bosses. Either i didn't killed the enemies in a certain way or the zone i should've stand, i didn't went thru it. I cleared the entire map, when i cheated and nothing.
When you are a bird and you walk into a teleporter, you do not teleport as a bird. You need to be on the ground to actually teleport.
A lot of enemy bug spawns. They spawned in the same place and outside of the map. 5 to 6 enemy in the same spot. It wasn't nice at all.
Maybe this is a bug too, idk. I have money to spend them on nothing. The shopkeeper sells useless stuff, because the RED text from how i read it, it says: That the one who attacks you, will be attacked by a ghost. Not you.
What is cool: the fact, that you can transform from a thing to another. A dark atmosphere. Nice spells.
What is uncool: the unfinished map.
