Death Weapon Revamp

[x1341x]

Thank you for replying to my question

[NEW]
INT + 25
DEX + 25
MATK + 15+(DeathMastery/500)% ->> (25% Max MATK)
Magical damage to All Races by (DeathMastery/250)% ->> (20% Max)
Gain 1% HP for every refine level (10% Max)
Class: Rod
Base MATK +20%

So When achieved Max deathmaster point ( 5.000 points ), the base will be gone and replaced with the max one? or it will be added more from the base one?

As of now, this weapon can give up to 45% MATK at maxed mastery. 20% by default, the weapon gives additional 15% matk bonus (35%) then the Death Mastery at 5000/500 = 10 +35 = 45%

assume I gain only 1.000 deathmastery point, what happen to the matk %?
Thank you in advance.
