"Malevolent Champion Focus:9 OR 75(depending on use)(recommended just 9 for the mods)"
Is what I'm referring to. There isn't any real reason to not use it so I've decided to put 75 into it. I don't really use AG that much, but I'm guessing I should. Atm (gone from level 14 to 50 in 6 hours) Silver Orcs go down to Skeletal Fortress, I don't even use Nether Allegiance. I just keep SF at ~ 26.0s regeneration so I can cast another once I exit the cave and reenter.
PS: Ofc, I have prioritised Shadow Veil, having it at lvl20+ asap (To get 80%+ Chance to stay invisible), iirc lvl25 gives you 100% with only 25% regen penalty.
