Pain waves increase their intensivity, speed and spread. You are now feeling like if you'd been skinned alive and burnt with melted tungsten from inside. [3] You manage to hold suicide thoughts inside your slowly-boiling brains, but you fall down to the floor and roll like a madman, as if it could help to cease pain. It doesn't. You teeth begin to crack, covering with a net of small fissures as you squeeze your jaws together from pain.
After a whole agonizing eternity you hear doctor returning. He is alone, though. He sees you rolling on the floor and hurries to you with a tiny flask filled with dark-green powder. He hardly manages to push your jaws apart and pour the quickly-made solution to your mouth.
For a moment, pain raises to it's highest peak, but then begins to weaken with significant speed. You look at the place your left arm was used to be: your whole shoulder and and, as you guess, half of your chest are now covered with a huge black net of burnished black traces, covering the whole surface of your skin so tight that the actual skin color can't be seen anymore.
Now you feel something different. Some kind of... inspiration? You feel that all your feelings become a bit sharper, then even more sharper, than something begins to turn inside out inside your guts and chest - it is not painful, but quite unusual. Your lungs seem to be filled with inert gas, but... you are somehow fine with that. Your guts feel stange - like if gallons of water would flow through it right now. Don't worry, your pants are clear. Your sight for a moment becomes so sharp that you are able to see the snow gleaming on the peak of mountain that you know is situated in at least 1000 miles from this place. You can hear like flies buzz over a shitter nearby. And smell it as well as thousands of new smells.
[Now there will be a roll for each of your senses to change somehow. Vision, smell, touch, hearing and taste. This is the order. 6 is ultimate improvement, 1 is complete reduction.]
[5] Your vision stays extremely sharp. Even for elf, you have an ultimate skill of that now.
[6] Your smell sense is an oblect of admiration of any hound now - you can feel thousands of smells right now. Not like each of them is pleasant, however.
[6] You now can say almost everything about any thing by touch - the way it was produced, it's complete composition and age. Your skin is now much more feelable now, however, and your usual clothes now seem to be extremely raw and scratchy.
[1] You are deaf now. You can hardly read by leaps, so that is a problem.
[4] Your taste is now slightly imroved - sure thing you now can become a proficient cuisine critic.
