The combination of Cradle of the Grave and Outrage abilities causes for some interesting behavior. Cradle of the Grave will always revive the character when it dies, then places it to the top of the action queue with 1 hp. Outrage will give the creature berserk which will make it damage itself by a % of how hard it hits, ontop of doubling the damage that it deals. What happens is as long as it can land the damage it will be able to attack forever. This strategy works on 95% of the enemies in the game. The last 5% can be dealt with by having other creatures augment it. Notable counter that I’ve found is dodge, shell and interrupt attack, shell is kind of a one time thing and so far I haven’t found a creature that has shell up before it attacks, interrupt attack is found on a single enemy and is a 25% chance. That leaves dodge being the only notable counter, so it does sort of keep it in check with being able to single handedly win the arena. I would have to do more testing with it to see how useable it is by putting Cradle of the Grave on a Lich Priest since it takes 10% of its own health during its attack.
If some sort of fix is in order then making Cradle of the Grave a 50% chance to be at the top of the queue would be a good step in my opinion. However since it requires a legendary artifact maybe it could be justified.
