I am wondering about the casting time of the spell granted by channel the gift when you target yourself and if it should count as a spell like ability:
If you target yourself with this spell, you may spontaneously cast any prepared spell of 3rd level or lower without expending its spell slot on your next turn (this aspect of the spell has no effect if you are a spontaneous caster). The spell that’s cast after channel the gift cannot have a casting time longer than 1 full round.
It fails to say what the action to cast the spell is or if it should be treated like an SLA.
Part of why I'm asking about SLA is the meaning of "spontaneously" from google search:
without apparent external cause or stimulus
