Prerequisite: Time Lord

The Time Lord has such an intuitive grasp of Mathematics that they are one of the few beings in the universe who understand Block Transfer Computation. Besides being a walking calculator, the Time Lord is particularly adept at handling structures, like the TARDIS, which are based on the mathematical creation of physical matter.

The Time Lord adds +3 to any roll involving Mathematics. This also applies to any repair or restructuring of the TARDIS itself. They can also apply the power of Block Transfer Computation to Jiggery Pokery, gaining a +1 to those rolls as well.
