I guess, you should spend more wyrd to become powerful for just a few minutes (if not seconds).
Did anyone read Mistborn from Brandon Sanderson? (great book btw

(might have spoilers)-> In the book "magic" is based on "burning" metals that you drink, but they are consumed. So you need to do things fast (like in 5 minutes or less) depending on the metal. If they don´t, they might die of metal poisoning!
The warrior/dervishe/psi can be a badass, but he needs one thing to be the badass and that is Wyrd.
My point is, I don´t want to give players a character that will rip a BB in half, storm the castle and save the princess with it being too easy. I want them to plan when to do stuff.
Other than Wyrd, the character can have a huge backlash on their stigma. Making it weak or more suceptible to certain things his stigma gives him, like hangover feelings, nausea, cramps, muscle pain, you name it.
Sorry for spamming.
