mythic spells on non mythic characters

[Lady-J]

would it be possible for a non mythic character to learn/cast a mythic version of a spell or create a similar spell via spell research?

There's a meta magic feat for that.

Specifically, you're looking for Ascendant Spell, which is a pretty nasty bite at +5 Spell Level.

looks like trying to make it via spell research it is. not worth a 6th level spell slot just to use mythic magic missile just wana replicate the mythic versions ability to bypass the shield spell maybe make a 2nd level spell version for the 2d4+1 damage
