The party all shush each other, not wishing to break the necessary concentration of Stamm.
"WHWHWHWHHWHWHWHW!" says the Mind Flayer, which is 'HAHAHHAHAAHHA' when you have a mouth full of tentacles. 'HAHAHAHHAHAHAHAHA' it also says telepathically, which it had to concentrate do do - resisting the temptation to imagine saying 'HAHAHHAHAHA' with a mouth filled with tentacles.
Stamm takes his chance in his opponent's hesitation to leap forward in a decisive and defistating attack. Sadly, the distracting caterpillar means Stamm doesn't noticie his untied boots, and decisively launches himself forward into the Mind Flayer's mouth.
A bit of an own goal really.
"Nooooooooooooooooooooooooooooo!" sobs Stamm.
"HWHWHWHHWHWHWHW!" mocks the Mind Flayer, flaying a mind and running off.
"Poor Stamm!" says the group, rushing forward to an almost comatose dwarf.
"He was my friend!" says Stamm finally. The group realise that the Mind Flayer has actually attacked the catepillar and made off with it, and not attacked Stamm. The group then decide to back off and give Stamm some space to grieve, mostly because they are trying not to laugh at the fact Stamm's brain is smaller than a caterpillar.
Eventually, pleased with themselves, the party carry onwards with a sad Stamm in tow. Go to 136, where this test has surely been passed. Surely. It's on to the end. Yup. No bout a doubt it!
