Servants of the Spider Queen

As the Rindherder Boys traipse around collecting pieces of the Lance of the Wolfen-Khan, they've pieced together a theme among their resistance, which has taken the form of nasty spider/dog hybrids. Like spiders, they are very comfortable with webs (unaffected by any of their effects) and can climb along walls, and all have a venomous bite that they pair with claws or scimitars. The Boys have witnessed a few different castes:

Kakkuu

• Big-dog-sized
• Near-animal intellect

Phisarazu

• Horse-sized
• Spits a glittering web that forces disadvantage on perception checks and grants advantage to attackers
• Can turn invisible at will.
• Can cast modify memory.
• Can summon other demons.
• Smart enough to impersonate a graduate-level wizard, but still dumb enough that a bunch of halflings could kick its ass.

Raklupis

• Large-bear-sized
• Spits a glob that explodes into a cloud that does massive poison damage and prevents speaking on a con save failure for anyone who starts a turn in its radius.
• Can cast suggestion.
• Can turn invisible at will.
• Not as dextrous as the smaller demons, but with a harder carapace and a boatload of hitpoints.
• Generally smarter than phisarazu. Still too dumb for the Rindherders.
