Reviving cut seems a little weak esp for a main starting skill. It regens for 4-5 turns, 1-2 hp per tick. (does magic affect regen rate?)
It also costs 20 sp which is pretty expensive compared to how little it heals. It seems very weak compared to soothing cut or Regen which lasts an eternity. Not to mention that the cut can miss.
If it was cheaper or lasted a little longer I'd feel like it was a decent skill.
