Great Weapon Master: All In

Great Weapon Master: All In is a Toggleable Passive Feature provided by the Great Weapon Master Feat that allows  Two-Handed or  Versatile weapon users to deal extra damage at the cost of reduced accuracy.

Description

When attacking with Heavy melee weapons you are Proficient with, Attack Rolls take a -5 penalty, but their damage increases by 10.

Notes

• Despite the description referencing Heavy weapons, this feature actually applies to any Two-Handed or Versatile melee weapons equipped with no off-hand.
• Great Weapon Master: All In does not need to be enabled in order to benefit from the Bonus Action extra attack provided by the Great Weapon Master Feat.
