Not likely for me. I haven't liked psionics in my D&D since 1e and I am not looking to change now.
I personally have always thought of arcane as the mental magic. I see psionics more likely socerery in that it is innate magic. In fact, in my D&D heart breaker there are (3) ways to have magic:
- Spiritual: magic from another source that you borrow - divine, pact magic, etc. (clerics, paladins, warlocks, druids, etc.)
- Arcane: magic harnessed from the ambient magic in the environment through study, words of power, foci, etc. (wizards, possibly artificers, etc.)
- Innate: magic harnessed from within you (psions, sorcerers, etc.)
The thing with my system is that the innate caster is not class dependent. Is a straight buff. So a fighter can also be Psion or sorcerer with the right bloodline (or similar) and so can a wizard or cleric. It is simply layered on top of what they already have.
