Ashuras arms
The ability to grow multiple arms that are exactly like the normal ones hence training effects the power of it
Anger boosts overall power and every kill gives a boost of power could reach Longinus level every 100th kill steals something from the thing killed weather it be mana stragth intelect and even dna or divinity even clan traits like the power of destruction
Any conflicts are stoped and the power changes to work together
Said powers can be passed on to kids
