These are used only with the Ninjitsu skill.
Animal / Minimum Skill / Description:
Squirrel / 20 / Transforms you into a Squirrel with no special abilities.
Ferret / 40 / Transforms you into a Ferret and gives +10 to Stealing skill.
Cu Sidhe / 60 / Transforms you into a Cu Sidhe which auto-self heals using Bandages.
Reptalon / 90 / Transforms you into a Reptalon giving you fire breath attacks.
These were on the Other Sylvan aswell as OSI and I know a lot of players would like to see them here including me.
Interesting ideas.
