Hey, you, I/L Mage. Yeah you.

(Elemental_Amplification%)*(Elemental_Weapon%) is correct.

And to Fiel if you mean that a person with 1999 magic wearing an E-wand would show their magic being 2498, then no the boost is applied on the regular calculated damage of the attack not directly to the stats. So for someone with 1234 magic hitting 100k regularly, with a 25% boost from an ele wand he would still have 1234 magic but hit 125k instead.

I don't think that Elemental Weapons and Amp are multiplied. I think they're added. If I add on +25% damage to my amped damage, it comes out high. However, if I look at my damage without amp, multiply that by .25, then add it on to amp it comes out more accurately.

An ele weapon + amp = 165%. An ele weapon * amp= 175%. Does any other AM wanna help with this?
