If anything, it's the other way around.That said, stunning does have the disadvantage that there are a fair number of types (construct, elemental, ooze, plant, undead) that are immune to it. Nothing is immune to dazing out of the box (though many effects which daze are mind-affecting, Fort save to negate, or otherwise blocked by other immunities). Still, "upgrading" by reducing the penalties but bypassing immunities somewhat better is at best a mixed bag.Originally Posted by SRD Condition Summary
Instead, I'd suggest adding daze to it in the case of the target being immune to stunning.
1Oh, hey, mind giving me a drive-by comment on school foci, attune focus, or maybe the orb of X rework?
