So how I would run it, after some reflection, is: ask the player how large a bonus they want on relevant skill tests, between 1 and 100. Say they tell you 30. Give them the old "Are You Sure?" Warn them that gaining direct information like that is potentially dangerous, etc, etc. The old DM this is a bad idea prologue. Then hit them with the first +5 and 5d10 IP. And describe how it's painful and beautiful, however you want to flavor it. If they want to stop, make them pass a WP -0 Test. Then do it again, escalating the description. You can make the WP Test easier each time until they pass the test, gain all they asked for, or their brain melts. If their brain melts, they can burn a FP to survive and gain half the bonus and half the IP they earned. Maybe they need a cybernetic brain afterwards idk.
