Most attacks vs 1 target in 1 turn: 22? Can anyone do better?

[WaroftheCrans]

You don't need action surges when you have arbitrarily many heads, not do you need to deal exactly 25 damage to yourself. Just bite off one of your heads, grow two more (and regain 20 HP), rest when you need to regain HP (can precast Goodberry as a Bard 17 if you want to jumpstart things by growing a few dozen heads right off the bat). Rinse and repeat until you have thousands of heads, if you want.

Of course in practice you'd never do this because it's pointless overkill, fencepost security--like putting up a wall a thousand feet high and green feet long. 3000 heads is no better than 100 heads for overcoming Dispel Magic. You'd be far better off True Polymorphing into an Atropal instead and summoning 3000 Wraiths instead.

Well, there is no set way to just bite off your head, and it really goes against the spirit of the challenge. Also, OOTS #326 comes to mind :)

My reason for listing 32 attacks is that's the most reasonable amount, and the amount Eldariel listed. Using permanent duration true polymorph just makes you into the monster, which is incredibly boring.
