So, I have only planned out half the AU so far, so feel free to suggest any ideas. :)

In this AU, a glitch has caused the potions to cause strange side effects, but the hermits have no clue >:)

I will also be using mob effects. There is not enough potions.

THIS IS SET IN SEASON SEVEN

Ok, here is a list of the Hermits I have some idea for:

Grian (he will have wings) - water breathing - Mermaid 

Wels - Regeneration - Wounds would heal in a second, but hearts would still lower

False - Slow falling - Wings (I like the idea of Winged!False)

Bdubs - Night vision - Can sleep and summon beds as soon as the sun goes down. 

Xisuma - Turtle master (lets ignore the fact he was a bee and strider and not a turtle last season and now an axolotl this season) - basically turtle but can't turtle into one (he can breathe in water etc.)

Tango - Fire res - immune to fire, and can summon fire

Impulse - Swiftness - controls time 

Doc - Leaping - can become a goat hybrid

Zed - Invis - can turn invisible

Iskall - Healing - always on full hearts

Cleo - Wither/Decay - anything touched DIES (including people)

Scar - Poisoned by bee - Can talk to animals but can't touch them (except Jellie, he can touch her. Why? Because Jellie is cute and Scar without Jellie is sad. Let's say she got stung as well.)

EDIT:

Cub - uses a totem against vexes - basically becomes an evoker, and can summon vexes and be a vex himself (Thank you Ember)

Stress - Glowing effect - can make things and herself glow. 

Thats all I got. 

Feel free to suggest anything for any other hermit. I couldn't think of anything for Mumbo, Stress, Ren, Xb, TFC, Cub, Etho, Hypno, Jevin, Joe, Keralis or Beef, but I might not include every hermit. 

EDIT: (Those in italics have been resolved)

Anyways, thank you for all the support. I broke before writing this chapter-thats-not-a-chapter, so good job :)
