In the interest of haunt shifting an undead creature into a carriage and getting the carriage to go fast, I am looking for what the haunting’s base creature should be. With templates, most creatures could be made undead, so we’re looking for:
- A creature that is, or can be made, undead
- Without getting above 8HD
- Featuring the highest available base walking speed
- Being controllable in a permanent manner by its method of creation or otherwise
- With as little ‘exotic material’ as possible – keep is as simple as we can.
