Arcanist Brand + Discharge. How does this work?

As stated above, I am thinking of doing this build for next league but still, I don't know about the interactions with the brand and the skill itself.

I had one thought that was bugging me from doing this build was, does the brand when it triggers the skill uses your own power/endurance/frenzy charges or is it completely separate and uses its own charges.

I may sound like an idiot and the same answer may be simple but I just want some clarification between the interaction on these two.

Imagine you are using Mjolner instead of Brand, should be pretty much the same mechanic regarding charges.

So in short - brand use your charges, as brand is your own skill.

How do you plan to generate charges? Romira, Volls or something else?

i think it will work the same way as it works with mine and totem, it does not work at all.

Skills used by the brand are your skills, and they will consume your charges. Brands are not their own entity like mines, traps, and totems, and Arcanist Brand simply functions as a trigger that overrides the point of origin for the spells it triggers.

So you can use Discharge with Arcanist Brand, but you will still need to maintain the charges, and it will still suffer from its 35% damage penalty.
