GREAT WEAPON FIGHTING
Type(s) Power
Prerequisite(s) Strength, (Brawn or Melee)
When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is lower. The weapon must have the two-handed or versatile property for you to gain this benefit.
Tier 2 You don't need to keep the reroll if it's lower.
Tier 3 Rather than rerolling, you just roll your damage twice as two separate pools and apply the greater one.
