Kligaxx's Chaos Blessing (Prerequisite: Paladin, level 12+)

You have been blessed with the same lingering boon as Kligaax, the legendary goblin paladin who slain the Demon Lord Orcus with a mighty Divine Smite. The blow—a critical hit—occurred within a Wild Magic Zone while Kligaax was under a Maximized Spell effect, resulting in a chaotic blessing that now empowers paladins who follow in his footsteps.

Ability Score Increase: Increase your Strength, Dexterity or Charisma score by 1, to a maximum of 20.

Chaotic Blessing: Whenever you cast Divine Smite, roll 1d4. On a result of 1, a Maximized Damage effect triggers (use the highest possible number for each damage die). This effect can occur a number of times equal to half your proficiency bonus (rounded down) before requiring a long rest.
