Bob's Empowering Death

When you reduce an enemy to 0 hitpoints, you can use your reaction fortify yourself with the defense of your felled foe. You gain your felled foe's damage type resistances for 1 round. Also, as an option, you can delay the activation of these damage resistances which you gain from your felled foe for up to 1 day. If you choose to delay the activation of the damage resistances, you must use your bonus action to invoke the resistances when you decide to activate them.
