I keep reading that the highest science check requires 170% skill, and it's mostly just for a laugh. Anyone know what that is? Or at least where to find it? Can anyone confirm that it even requires this much skill?
Ahh, you're definitely right on the hard requirement. I always aim for 121 or so and usually have to reload or level up and get skill points in.
The highest hard check is 175%, for downloading an useless "word list" from terminals on Enclave oil rig.
