I was thinking of party tonics that:
Changes form or Appearance,or both of the character(not required).
Gives a Skill/s that has a benefit or just a benefit,or both.
But no Healing/Power.
But it gives faction/emotes/forms/costumes/effects/Items/titles and achievements/glowing body part.
What do you think?
And if you have an idea for a tonic tell us.
