Looks fun! My only concern is the radius on Whispering Trees. Also an issue would be that you can trade the Wonder of Nature items, which means you can make any champ into a channeler. Maybe consider making it cost 1 essence, and give 2 essence when the item is used.

Oh yeah, it's not "Heavenfall's Elf race", it's a community project, I am just involved.

Edit: You should give some of the tactical spells a 9999 cooldown to prevent them being cast more than once by the same caster.

Oh, about the trees the radius is not as bad as you'd think.  I tried it out and it is large, but not any more than a mid-game Sov would be.  Considering that spell is level 7 I would think it wouldn't be overpowered.

There is a bug though in the game where if you exit a game, all reveal effects are erased even from a saved game.

That's why you need a large number, so there's no chance it will refresh.

The problem with that is that all the spells I've added in should be recastable. Ideally some would only be available once per battle, or only have one active at a time. Unfortunately both of the tags that would let you do that don't work with tactical spells.

Actually, Giving tactical spells a cooldown of -1 is actually better. A cooldown of -1 does not crash the game and tell the game that the spell never cools down. This is probably the more correct way to do tactical cooldowns.

Finally got my primary system working again, so I'll look through the spells to get them updated for 1.09.
