How many level 20 PCs with Tiamat (CR 30) on their side would treat Asmodeus (CR 40) as a Hard encounter? reproduces the stat block for Tiamat in its entirety. That struck me as reproducing rather more copyrighted material than is necessary, so I hid it in an HTML comment and left a (mainsite) comment to the effect. (Revision 5)
It's been brought back out into the open. I don't want to start an edit war, but I think something like "I'm using Tiamat's stats from Rise of Tiamat" would give potential answerers enough information to go on without reproducing non-SRD material.
Should this question post that whole stat block?
