Spirit of Rage exploit **minor spoilers

[Lari]

Played a warrior too, but i didn't relay so heavy on spirit of rage. Probably my bad, but usually the battles ended by turn 3-4, never use soul drain a single time, not even black hole (so not taking the dmg xp bonus at all), my troop just inflict enough damage; target on the first round, and time back on the second one, give me a few losses at the end of battle, if none and i didn't care too much about them anyway. No doubt that u reached level 30, u made an heavy use of them (which probably is the right strategy for warriors) I also liked to have high rage, to max out crits chances/dmg, so i was a little greedy on using rage demanding abilities.

You're telling me, I overupgraded my soul drain and it ended up costing me 70 rage per use, was waiting for that last rage reduction upgrade all the way until lvl30 but it never came. <_< Luckily I had +50% rage from the baby and +50% rage from Pain Skull (which was 2 enemies short of being upgraded at the end of the game by the way, waste of bloody artifact slot) so getting enough rage to cast it didn't prove that much of a problem. Black hole is useless though.

Haahaha the game really should have to say you when you take the last upgrade
70 for 50% is really costly, 35 for 40% is kinda better, a shame also that you can't undercast a spirit of rage like u can with spells, would have been a nice feature!

Yeah, I would have loved to use lower levels of the abilities sometimes, but there's a lot more than 3 levels so you'd need a lot of buttons or a new menu for it.
