they have multiple converters. if lets say i use a fire resist pot, and they decided to go water endow, it will do me more harm than good. ive seen knights pvp vid and they carry all 4 elemental converters.
i knew you would say that! they cant endow all 4 converters at the same time tho, you can also carry various resistant potions.
also, as far as I know, you don't get ur full damage multiplied by the element in rt, only part of the damage. correct me if im wrong.
also, everybody goes + damage to neutral. not sure whats the max you can get. but if they have 20% damage to neutral, by using a potion you are eliminating that 20%
you have 1/4 chance to use a weak element, in which case, you would take 25% damage, which is just 5% more than their neutral, and if they have 25% neutral, its basically the same. on top of that, you have 2/4 chance to use an element with no advantage or disadvantage, in which case you still negate their damage to neutral, and 1/4 chance to take 75% LESS elemental damage and negate their damage to neutral.
bss is also a thing. not sure if many ppl use cursed water tho, since they risk hitting someone with ed and doing no damage.
bad thing would be, if lets say, they have a weapon with extra damage to fire and they use water endow while u use a fire potion . but everybody goes damage to neutral o.o
