DBs can roll 10 overwhelming with medium daiklaves thanks to Demon-Crushing Wolf Bite, even with Aegis of Invincible Might + Iron Kettle Body getting that down to 3 dice you are only resetting essence-gathering temper every 4-5th hit, and that assumes they let you trigger Aegis. If you actually build DBs to fight celestials they become pretty hard to take down when they have decent numbers.
