The Elder Scrolls: Tamriel

Immediately after taking the Attack action with an unarmed strike, make two additional unarmed strikes as part of this move. Each strike deals 1d4 + DEX modifier bludgeoning damage. These extra strikes do not benefit from additional damage modifiers. At level 5, make three strikes; each deals 1d6 + DEX. At level 10, make four strikes; each deals 1d8 + DEX. At level 15, your unarmed strikes count as magical, and crits with this move cause the target to make a CON save (DC = 8 + Proficiency + DEX) or be staggered (disadvantage on attack rolls until end of its next turn).
