Hmmm, I'd thought "use tentacles against" just meant for grappling purposes. If we mean it can only attack a PC with 2 tentacles in a round, we might want to clarify that.
It seems pretty clear what an "attack" is in this context. If we meant only grapple check we'd have said so.
Still, if you can think of any changes or additions to make the wording clearer I'd be happy to see it.
But I can certainly see your logic --- I always feel like I'm guessing at these levels.
Yes, Challenge Rating is a very inexact science, especially at higher levels. That an how easy a monster to defeat is often so context-dependent that it basically depends on what spell-and-equipment loadout the PCs happened to choose that day.
CR 20 is ok by me if it works for Arnwyn too.
OK, let's wait for him.
