Kobold’s Fury 2014
1st-level transmutation
Your touch infuses the rage of a threatened kobold into the target. The target has advantage on melee weapon attacks until the end of its next turn. In addition, its next successful melee weapon attack against a creature larger than itself does an additional 2d8 damage.
