The rules
Every 5 levels a Perk: choose 1 of 2 passives (Woodcutting 15: Heartseeker (+heartwood chance) or Longstroke (+yield on tended tasks)). Perks can be re-chosen at a Waystone for a Toll of that skill's labor (player-driven respec: you pay in the skill's own goods).
At each stratum cap a Specialization, exclusive: Woodcutting: Heartwood Seeker / Pale Feller (Drafts' wood) / Warden-Feller (can fell Warden parts). Specializations gate recipes and materials others must buy from you (ADR-007 interdependence).
