It says it does 8-12 damage, but doesn't seem to do more than 5 damage. Anyone know why?

Q0 Spear Damage Is weird

whatever your hitting has armor

It's not (only) because of armor. The listed damage is true assuming you have 12 spear mastery. It follows this formula otherwise. Plugging in AttributeLevel = 0 results in an actual damage that is around 35 % of the base damage.
