One time I had an evil party that was seeking to revive a dead god they worshiped. In order to do so they needed to steal an artifact from a temple...that was guarded by a solar and a bunch of other angels.

Now I expected them to go all Shadowrun and spy, and sneak, and steal it like good master thieves.

No....they just kick down the door, and somehow I do not fricken know how, Kill 2 solar angels, 2 astral devas, steal the artifact, and kill about 6 more angels on the way out.

And no this wasn't at a level where you should be able to do that. This party was level 15, EIGHT levels below the Solar's CR.
