Art shows a muscular draksar with brass knuckles. "Who needs wizards? who needs archers? What Valdac needs is more good old fashioned melee beaters." Attack physical (range 1) Suppress magic (all magic damage is reduced by 20%) Slow range (attacks made at range 3 or greater all cost +1 AP) -this is the mindslicer obolisk ability - Upgrades = whatever Let's give physical melee beaters some love. A no new abilities version could have weaken spells instead.
I don't see any new abilities? There already is a lizard in SL that does the exact thing you said - applies a negative 20% magic damage amplification, which doesn't stack.
