Not sure if this is a official reaction, but I know Solasta allows casters to cast featherfall as a reaction when they or a party member near them are knocked off a cliff, would be neat if they added as a option for BG3 as well. As for Daylight, hope they make it look more like a godbeam out of a cloud, or if not, less like a orb like it does in solasta xD.
Featherfall is only a reaction per 5e. Larian homebrew it and TA respected RAW.
I also hope they will make it a reaction... The only point of using it currently is to jump in the underdark hole or eventually "just in case someone push you in combat". It never really worth to use it at all.
I'd rather like to be able to use it as the reaction it should be.
