A few questions about imbue builds

do imbued weapons and fists add the magic’s, damage, speed, size, and damage over time to whatever is imbued? or is it just the magic? and can thermo fist weapons apply burning?

Yes all of these, as well as status effects & synergies if they have any

I haven’t tested this myself but I assume it would at high heat

thermo fist weapons do indeed apply burning

would that make magic speed equal attack speed, or still the speed of projectiles? like fist’s shot ability, dagger throw, and flying slash?

I think it averages out the stats between the fighting style and the weapon

i misworded that. which one of the two would magic speed combine with on a melee?

The speed of m1s as well as the projectile speed
