When you cut a headspider out of a victim, the headspider should pop back out

[Slacker Magician]

I don't think it creates any tedium. It basically adds an additional fight the tediousness of the surgery which previously is just boring if you know what you're doing. I've never heard anyone say that changeling surgery is a crap shoot. It works all the time, but it can take a few tries. I'd say that debraining and cloning is a more dangerous option because if the headspider has already taken over by the time they die, then you're cloning a changeling. Plus, I've never been a fan of considering murder-then-cloning a medical procedure to cure problems.

There is no danger of cloning a ling, as you can just de-skull the corpse at no risk to see if its taken over before the death occurred or not as it turns the host's skull into the ling-style skull.

Its more of a crap shoot if you don't have the Medical training trait, which greatly reduces the chance of cutting out the parasite quickly sometimes taking 6 or more cuts to remove it, with no guarantee on if the change has occurred yet until you get the blurred vision from a NT sting.

Addendum, the host is also very likely stunned due to the intrusion of the head spider, unless its already had some time pass, so you're asking for an unarmed doctor to deal with a 80 HP player controlled critter, that can instantly render them unconscious if it gets unstunned, repeating the process

Doctors usually only have up to a 10 damage extinguisher, so it'd take a minimum of 8 hits to down it before it just jumps into either the previous host, or the doctor to fully restore its HP, so i'd have to either have a bunch of nearby folks or power-game and grab a hammer or phaser, which I really shouldn't have to do as a doctor to complete my job.

The tedium comes in that it just adds an extra thing, i'd rather get someone back into the round and playing, rather than having to hassle with a head spider over and over, if that makes sense.
