suggestion: make instant aegis armor and effect apply in the same tick it was cast in

i'm not sure if this is a bug, but it is a bit frustrating. for high level effects it necessitates giving the armor ludicrous durability just for the effect to be active for more than half of the armor's lifetime.

especially given the "instant" part of the name, i think it might be better if the effect became active in the same tick as the armor, as if casting a zenith. it would allow for more creative and efficient uses of the armor, like using hexchanting or hierophantics to deliver quick effects, well, instantly, to react to danger.

edit to add: further testing shows that the armor itself doesn't seem to equip in the same tick either! attempting to use instant aegis to reduce incoming damage using a hexchanting chestplate doesn't work at all. it'd be pretty neat if it did!

Instantly applying effect: Maybe. I currently have the armor (re)apply the effect every 100 ticks for performance reasons, but doing it one extra time probably wouldn't cause any issues.
Equipping same-tick: I'm 99% certain this already happens, the spell calls player.equipStack in its cast function, and something would have to be seriously weird with base hex for that to be called a tick later than the rest of the cast. That chestplate casts a hex in response to being hit, yes? I would guess it just triggers too late for the hex to interfere with the hit.

hmm, weird. the amethyst chestplate casts when hit, but BEFORE damage is taken. one of the most popular use-cases for this is to apply an absorption effect for 1 tick with a level just high enough to completely cancel incoming damage. so the hex definitely casts before damage is taken!

i fear this could be some messed up vanilla thing then? maybe equipping armor in vanilla doesn't have an effect until the next tick or something.

i will test this by using hexical's hopper to equip physical armor on hit, to try and verify whether this is specific to instant aegis or just normal armor behavior. will report back!
