A Jack of One Trade is a Master of All
Uncommon23.2%ObjectiveOptional
Mastered one of the four stat types.
Buy every skill in one of the four stat trees (Strength, Dexterity, Charm or Intellect) from the Skills menu. Pick whichever tree you've sunk the most into and mop up its remaining nodes - you earn plenty of skill points across a full run, so one fully-bought tree is comfortably doable well before the end.
