It might have a low chance of success, or take more time, energy, or resources, depending on skill level, but it should be doable. No fucking needing a level in a specific class just to get permission to wipe your own fucking ass.
Unlocking new abilities is cool in video games. Locking them away doesn't work in TTRPGs because it stifles creativity and improvisation, so everyone is just staring as their character sheet to see what they can do and never open the rulebook or ask questions about their environment.
Of course, when it comes to extraordinary abilities like magic, super powers, cybernetics, etc., it's fine to totally lock some of those away for later progression. But the system should still have room for improvisation with the powers you do have. Like burning more spell energy to cast your firebolt spell faster or at a higher level, taking a spellcasting roll to reshape it into a line or cone rather than a spherical explosion, or tuning it down to light a candle or cigar. You shouldn't need a separate spell or metamagic for absolutely everything, or at least, to have permission to even try something different at a chance of failure or some extra cost.
