I think it's nice to use the retainers as more fleshed out characters who grows with the players. The level 10 ability is very neat.
Some feedback I had while reading:
- Revengeance is way too powerfull IMO: removing an elite or platoon enemy is already too strong, but damage weakness 5 for the whole encounter with no possibility to remove it is just broken
- I think Cleanse is too strong too, I might be wrong there though
- Rejuvenating Blast says "Each enemy in the area takes the damage of Hurl Magic": which tier are we talking about? Do you have to roll for each enemy? Once?
- I understand this is due to the page limit but the way the Scout abilities are displayed is a bit confusing
- Dampening Field is similar to the Null ability Absorbtion Field, which costs 7 and only affect enemies in the Null Field (so 2 aura), so it feels a bit strong comparatively
