Demon Set vs Zubei Set

[bowlcut gang 0]

Which one gives more matk on an SH with +12 int tats? And why are zubei set bonuses so scuffed (minus 5% mp regen)?

And last but not least, will B grade set bonuses get buffed on Zaken patch?

Demon gives you more more M.attack but Zubie gives more MP and MP recovery.

Can't say which of those will give you more m.atk (my guess is that +4 INT will give you more m.atk tho), but you can check what the set bonuses will look like on 2.5 patch: https://l2wiki.com/classic/Armor_Sets (the wiki is on newer patch but I believe there were no major changes with set bonuses) - generally speaking you should be aiming at Blue Wolf set anyway since it's the only one that gives you a stun resist, which is extremelly important in PvP. Give or take few points of m.atk don't matter as much as the stun resist here

+30% resistance from very low or non resistance at all is still a low stat. You will never realise you have that buff,

I was more interested in it for the purpose of PvE. Stun resist can't be all that important if most mages choose Dark Crystal over Majestic robe.

It's probably noticeable when stacked with EE stun resist buff.
