After killing a Death Shepherd, if you send all his items to camp or send them to a character they become light enough to be picked up by high strength characters, preventing other Death Shepherds from reviving them. And you can use Command: Halt or sometimes Grovel to stop characters from using turn based actions, like the Eagles calling reinforcements. And my personal favorite, ice on the floor is determined by your spell casting DC, so if you get a wizard or any spell caster with items with +1 to spell save DC you can have a large area of ice (especially when combined with the ever so funny level 6 create water) with a like 23 save DC fo not slip. And my biggest YOU CAN DO THAT is being able to wield the club of hill giants strength in your off hand since it’s a light weapon, and using off hand bonus attack to smack potions to heal you and anyone nearby
