Steps to reproduce

Cast a BRD debuff on a Colibri that can mimic (note: it must not be fully resisted)

Expected behavior

If a mob is able to cast a spell, it can be assumed that it has sufficient skill to do so, even if it's not a job that has the skill for it natively. Example, Colibri mimicking BRD debuffs can reliably land them on players on retail, but they are not able to do so on LSB. We know that Colibri don't have BRD as either of its jobs, so it's not as if it's getting singing skill from that.
