So, what are the different properties of elemental attacks?

i kind of want to unearth this older thread with things i wondered about.

so as you guys already said, fire deals DoT, ice freezes and enemy, making them prone to attacks. electric shocks them for a bit, working like a stun, and plague should do DoT as well, but i could not manage to pull it off.

so my main question is, are there enemy weaknesses and resistances implemented?

like for example, do the fire bomb mages get burned as well, and if yes, is it shorter than for other enemies, which would be a sign for resistance?

and is there some stone-paper-scissor like system? like are for example enemies that deal plague dmg to the player less susceptible to plague bot more vulnerable to for example fire, making them easier to enflame?

or do shielded enemies, which take less raw dmg until poise break take more dmg from lightning or ice?
