Bartabis' Will

A shard from Bartabis’s battle axe twisted about with hempen twine and attached to a golden chain. 

While worn, the wearer can summon the will of Bartabis to have the following effects, each of which can be used once and cannot be used again until you finish a long rest.  

• Bartabis' spirit appears and flexes his muscles mightily to absorb the impact of an attack which affects you. This effect increases your AC or the result of a DEX saving throw by 5, and you gain resistance to all damage received from that attack. You can use this result before or after you know the result of the saving throw or attack. 
• Bartabis' spirit appears and throws the wearer of size large or smaller up to 9d10 feet. Bartabis shouts "Cannonball!" and can be heard from 100 feet away.
