Masochist

You gain pleasure from pain and sometimes can't tell the two sensations apart. You gain the following benefits:

• When you take damage equal to your level or more in a single round, you gain a +1 bonus on all types of rolls for the next round.
• As a bonus action, you can use a melee weapon to deal damage to yourself equal to the weapon's normal damage. Until the end of your next turn, you gain resistance to bludgeoning, piercing, and slashing damage from all attacks. This effect can't be stacked.
