if i understand correctly right now it only works against effects resistable and spells clearly stating they can be resisted
(even though on enemy champions i seem to deal a bit less dmg maybe its some item or trait or spell dunno)
anyway i think at least big monsters should have some way to reduce incoming dmg
i fought a drak with 150 hp or so and he had 100 spell resist and with like 4-5 casts i could take him down, its not so cool tbh
also tbh im not quite fond of "all in" mechanics, rng is so bad and unfun, imo everything should be like % scaling to be perfect
or a system like wow vanilla with a gaussian roll and 0 25 50 75 reduction
anyway opinions? it seems like a weak stat for now
