D&D (2024) Psionics: What Do You Want?

[mellored]

you'll lose the ability to do big stuff later in the day,

That's why I added a 1/long rest, you succeed, and it's short rest recharge.

Still not claiming it to be the best for Psion.

cooldown-based. So when you use a skill/spell, you can't use that particular skill/spell again for 2-6 rounds.

I like those for video games, but it's a bit too much to track.

But "can't cast 2 turns in a row" would only require you to know what you used last round. That's could work.
