You got your tadpole in my troll!

[Savage Wombat]

A mind flayer decides to insert a illithid tadpole into a troll's head.

The tadpole begins to devour the troll's brain.

The troll's brain regenerates.

The tadpole grows in size - but the troll's brain isn't losing mass.

At the same time, the troll's immune system is undoubtedly trying to kill the tadpole. But illithids are probably used to this sort of thing.

So...


What do you think we wind up with?

But illithids are probably used to this sort of thing.

Who's to say? I think it's perfectly reasonable to rule that any creature with Regeneration would be immune to ceremorphosis (or whatever it was called). I'd say the Troll's amped-up immune system kills the hell out of that tadpole.

What do you think we wind up with?

A troll, I think. Any defenses brought in by the tadpole would be delivered under the assumption that the host creature would die soon after insemination. Since the troll wouldn't die, it's immune system would soon be able to overcome the defenses and destroy the tadpole-ish invader.

But that's the boring answer. The fun answer is a Troll-Illithid crossbreed with a deep hatred of its parent creatures due to the lenghty torment involved in the tadpole repeatedly battling the troll's immune system. Maybe such a creature has open sores on its head and torso out of which flow a mixture of psionically imbued regenerative fluids which upon landing on and then burrowing into the earth begin to blight the land as the dark offspring of this Thing That Should Not Be crawl out of the ground on a mission to punish all life for being that which it is a mockery of.

Maybe.

Sounds like a prime way to get a Neothelid eventually if the giant tadpole gets ejected from the troll's regenerating brain and isn't killed in the process.

I thought it was Neothelid. Am I being ... anal? ... pedantic? ... all of the above?

Or is there both Neolithid AND Neothelid? Yikes.

 

[Ankh-Morpork Guard]

Technically, by the 3e/3.5e rules, you'd have a Half-Illithid Troll.

Its exact abilities and such would depend on the HD of the Troll, and I don't remember the details off the top of my head. of course, that does depend on whether the Troll's Regeneration prevents the brain eating or not

 

[Raging Epistaxis]

I'll be the first to admit I know little to nothing about the intricacies of the illithid lifecycle, but wouldn't that create a Trillith? From Piratecat's story hour, somewhere early on while the DoD are still in Eversink.

Meh. Get more tadpoles. There's enough for everybody!
