Psycasters get some psyfocus from pruning.
As far as my testing has done, so far it seems to be compatible with the following:

Note: For some reason I seem to be having some trouble adding a pretick action to an already-existing Toil, so this mod re-implements the pruning JobDriver to add a psyfocus gain to the prune Toil. If any other modders are experienced in modifying jobs like this, I can share the source code of the Harmony patching I was trying to do.
