Lots of stuff here, but the basics of the class seem really exciting to play:

• Use it to model characters like Jean Grey from X-Men or Eleven from Stranger Things.
• No spell slots.
• When you “manifest” your power, you roll a dice, and if you roll too low you take “strain”.
• Strain is cumulative, you get some choice in how it effects you, does things like give disadvantage on certain checks, reduces speed, prevents dodge/disengage action, etc.
• Max strain increases with level. If you exceed max strain you die. But you know when you’re at max strain and get to make the choice of whether or not to manifest your power and risk death.
• Strain can clear on rests.
