From DaevanionNode: skill nodes add levels to one skill. The path cost counts every node on the cheapest way there from the board's start (our calculation, as in the planner).

Gear: soul-binding skill effects

Top, Legs, Helm, Pauldrons, Gloves, Shoes… (1,772 items): soul binding draws up to 3 skill effects, each landing with 20%; a landed effect picks Protection Circle 1,000 times in 10,000 and adds +1 level.

Chance one item gets it: 5.88% — 1 − (1 − 20% × 10%)3, our calculation, assuming the draws are independent.
