how about some spells that can use that reaction slot?
Targeting Reticle T1
School transmutation
Casting Time reaction
Range 30 feet
Targets one ally making an attack roll
Duration instantaneous
Saving Throw Will negates (harmless); Spell Resistance yes (harmless)
The target gains a 1d6 insight bonus to an attack roll they are making.
If you can help, you can also hurt!
Scramble T1
School transmutation
Casting Time reaction
Range 30 feet
Targets one enemy making an attack roll
Duration instantaneous
Saving Throw Will negates; Spell Resistance yes
You scramble what the target sees if it fails its saving throw and has a 1d6 circumstance penalty to an attack roll they are making.
