How much damage would shoving a portable hole into a portable hole do? I vaguely remember a former DM of mine describing the resulting cataclysmic explosion. He might have been over exaggerating though.
Portable hole into portable hole? By strict RAW, none at all.
You will, however, be inside someone's A-Hole.
It's the best place to be!
Oh god... Lycanthro is our resident gay furry isn't he? So when he says this he could mean... *Winces*
Keep up, will you? Everyone else already knows this by now.
Also, what about a monk/kensai that gets throwing and distance on his body, then gets an arbitrarily high number of attacks somehow? (Re: Speed Boosts)
Strictly speaking, his body parts fly off and slap his opponents in the face, only to return to him. Or, if they're not returning, they just flop there and he no longer has an Unarmed Strike until he moves to that spot to pick them up. Interestingly, since any part of the Monk's body can be used to make an attack, this means he no longer has any parts of his body, but he still has all his other statistics (other than his unarmed strike). Again, just strictly speaking from the rules.
