Super Noob Question

Hi,

I read this forum and i don't know what is things like Max damage sword, 15^50, 20/20, what is this thing???

Max damage on sword = 15-22 damage
15^50 = +15% damage while health is above 50%
20/20 = 20% Armor Penetration/20% chance

Max dmg = Most damage a weapon of a type can do
15^50 = +15% dmg while health is above 50%
20/20 = ususally 20% chance to halve cast time / 20% chance to halve recharge time of X magic spells. Sometimes 20/20 refers to 20% chance to grant armor penetration +20%

Thanks for saying 90% of what I just said (;
