Trickery Domain: As bad as it seems?

[Man_Over_Game]

But it's not a spell, as I read it, so "dispelling it" isn't an option for the enemy. What they can do is recognize that it's an illusion and ignore it. Losing concentration is a matter of hitting the cleric, not the illusion, and cleric failing the con save.

Dispel doesn't have to target the effects of a spell; it works fine on generic magical abilities too as long as they're identified as "magical".

The question is whether the illusion is technically considered magical or not. I can't read up on it to determine if it's explicitly labeled as "magical", and it wouldn't make sense if it wasn't, but that's a possibility.
