Ah yes, the old but not good "but their INT!" chestnut.
The fact remains, Spirit Guardians single-handedly shuts down the "bounded accuracy means Orcs remain relevant" argument.
And since Clerics are the ones that get it, I felt it relevant to the thread's topic [emoji846]
Huh?
Not sure why you feel the need to defend the relevancy of you posting it here. Did anyone challenge or question that?
Your faith that your conclusion or opinion is "fact" is interesting but hardly compelling. Just because suicidal creatures arexstopped by short radius ongoing AoEs doesnt make any claim about mobs untrue, unless one assumes "no matter how stupidly played" was a part of it. By that logic, a cliff could "prove it untrue" if one simply assumes the gnolls (or is it now orcs from your in-game action?) if its between the PCs snd them so the gnorcs charge off the cliff to their doom.
But hey, any GM can change stat blocks, lower creatures zintan or just ignore whatever traits or rules they want to prove a point (to themselves at least.)
But, again, they even went into the challenges and big disparity in CR thing in the DMG, so, really, whatever partial lacking context straw position you are seeking to slay has really been covered in print. A bunch of gnolls (baseline models - not assuming leaders and casters and other such) would only be counted for difficulty if the GM saw in the situation and circumstance that they were going to be significant.
Outside of that, they would be more like mobile scenery - terrain issues you have to deal with. No more relevant to bounded accuracy than a river. For 5th level PCs they serve as an example of how the PCs have advanced beyond certain threats. Water Breathing and/or Flying removes the River challenge if it's simple just like Spirit Guardians can remove the hoard of the mindless gnorcs on parade.
Really, it sounds more like dome ehite room theory foisted into a session for whatever purpose the GM had in mind. Cannot say I have ever seen a GM run it that way, or even close, in actual play with creatures smarter than (or even as smart as ) common animals (range from 2-5 typically.)
But hey, if thats all the "proof"
you need, that's informative so thanks.
