Manipulation

[Yukio]

And pay four more CPs? What's more, you can *only* use Master's Mend on a 40 Durability synth when Durability is at 10. That's another limitation. Face it, Manipulation is useful.

I generally never use Master's Mend I unless I am at 10 durability and I know I will not have CP to do another non-durability consuming move. 4 CP actually makes a huge difference. To put into context, tricks of the trade restores 20 CP, so the 4 CP difference could be your Byergot's Blessing or Steady Hand.
