EDIT: I just realized that this whole issue stemmed from a really big dumb moment I had. I didn't even realize that changing the parameter was actually increasing the Max HP, not decreasing it. Sometimes I have these moments that make me question my brain pattern. The advice about changing the parameter actually did work and I was too much of a moron to notice. I don't blame you guys for possibly being annoyed at my stupidity. If you aren't annoyed, then you're all amazing. Thank you for your patience, I really appreciate it. ~*~ In the game I am currently making, you can enter secret holes underground and interact with a fairy who will give you certain boosts (i.e. boost max hp/mp, teach you a new skill). It's kinda inspired by the Zelda games. I already know how to add magic tutors to the game, but I have no idea how to give party members a max hp/mp boost outside of battle. I tried looking elsewhere but have had no such luck. Is it even possible to do this? If so, then how?
