Still struggling a bit with my character build: thought taking a level of Tough would solve my defensive woes, which it did, but then realized that'd mean loosing his Mentor Spirit Talent... Back to the drawing board.
Comments and suggestions:
Touch weapon property could use a little flexibility, I think. Something like: "User can choose to either take +2 tohit without Str or Dex bonuses to damage (light touch version) OR add their usual bonuses to attack and damage ('hit them with the stun stick over the head' version)"? Makes sense in a RL kind of way too.
Lots of Feats to get bonuses on melee and range attacks, but none for Conjuring or Casting... A deliberate choice? Maybe feats that up your Cha (only with spirits), or extending some of the combat-oriented bonuses to include spell-casting attack rolls? In general, as is it seems impossible to get a magic-user's Casting and Conjuring bonuses up to the +7 heights the other PCs all have in their main area of expertise. (Apparently the best conjurers are elves, the best hermetic casters are humans (though not very), and the best shaman casters are dwarves... uh.)
Cyberware beneficial for magic-users? Temporary Int, Wis or Cha overdrives? Parallel passive processing or schizophrenic mind-splits to quicken/anchor (1) spells or spirits? Or maye Damage Comp that works with overcasting damage?
Multiclassing: I think you're missing "Skill" in the 2 proficiency choices? Maybe also add "Equipment" to the list of 2 proficiencies you can choose? Maybe bundle up Tools and Languages together while we're at it since they aren't much by themselves?
So. Much. Stuff! My god, you must have spent an eternity on this...
