Thornback soul

Carry a compatible empty Soul Gem and select a living Thornback. Mark it through Summoning before the kill; binding pays essence and a failed capture returns the gem. Base capture chance grows by 0.2 percentage points per Summoning level above 55, capped at 35% including bonuses. Captured souls are individual items. Manifest one companion at a time. Upkeep consumes essence while online; logout pauses the active energy clock. Injured stored souls recover one HP per 60 seconds of real time, including offline and banked time.

8% shorter Herblore work cycles.

Bind a living creature within 6 m and clear line of sight. Binding costs 3 base Arcane essence, plus one bonus action if already in combat; you must contribute to the creature's defeat. A failed capture returns the empty gem, not the essence. Any Soul Gem of the minimum tier or higher is compatible, and success preserves the tier you chose. Manifesting a healthy captured soul in combat costs one action on your turn. Unused paid energy is retained; if no paid energy remains, manifestation purchases the next minute. Essence-cost talents can reduce paid costs, with a minimum cost of one.

A completed, genuinely assisted resource or work cycle awards 1 base Summoning XP. Following, elapsed time and toggling the companion grant no XP. Skill and activity requirements still apply.
