Magic Dmg Or Magic Attack Bonus

Hello, So ive been reading many forums and math calculators and everyone is seeming to have a dif thought on it. What really is better for CoR Magic Attack Bonus or Magic Damage + ? cuz i mean rostrums have no magic attack bonus but i mean like a weapon from ambuscade has both wouldnt that be better for ws ?

Magic attack bonus is better. You don't use Rostam because it makes your Leadens stronger. You use it for TP generation.

MDMG has a small effect on Weapon Skills due to being added after the fTP multiplier. It's more important on elemental nukes where there is no fTP component at all.

Almost always MAB will win but there are times a ton of MDMG will win vs something with very little MAB. For COR's WF and Leaden I made this:

What's nice with the new Ambu weapons is they have some of the highest MDMG we've seen on Main/Sub for COR along with MAB too.
