Im a Prophet 75lvl. Im wearing Tallum Robe, and full set of Majestic rings, earings and neckless. My MP is 3994. So I though that it would be good to buy a Ghoul's Staff w/Mana up for pve and full parties. It says it gives 30% MP.
3994 + 30% = 5192.
My MP holding my new Staff is 4898!!!! WHY?
I took off my Tallum and all the Majestic.
My MP then 3329 + 30% = 4327
but holding the Ghoul's Staff my MP is 4233 !!!!
the 30% is probably added into the equation before other things are added in. So this would mean it isnt taking 30% of your 3994 mp. It is taking 30% of some other mp total, then adding in other mp bonus's afterwords.
