(he/him)advocate for 5e psionics
that fix goes under giving them a unique spell list.I mean that's basically the strike/smite spells of paladin, ranger, and hexblade.
You bonus action to cast the spell, and then when your next weapon attack hits the effect goes off. Searing smite, ensnaring strike, and lightning arrow are all examples.
This is very similar to the swordmage spells in 4e. But in 5e, they barred the arcane classes from accessing spells like this. Depriving them of their signature feature while giving out that feature to the other classes.
