Vampire
Raises how many Vampirism abilities can be equipped, from two up to four. With day and night carrying separate loadouts, slot count decides how much of the night kit is actually reachable in a fight. Unlike its two counterparts it needs no manual — what it needs is Corruption, at 4, 7 and 11 for the three ranks. That makes it the only ability-slot perk whose ladder is paced by something other than skill points: the fourth slot is not a purchase you can bring forward, it is a purchase that waits until Coen has fed enough. The points and time are the same as the other two — 1, 1 and 2 points, one time segment per rank.
Each rank is bought separately. Point costs are unpublished except where stated.
The rank ladder — point cost, time cost, slot count, and for Vrakhiri Might the Corruption thresholds — is published exactly by a first-hand retail guide, and is the only exact per-rank costing any source gives for any node. What it does not give is the rest of the tree: where this node sits relative to anything other than its own prerequisite is still unpublished, and nothing here is extrapolated to its neighbours. Vrakhiri is an in-world term the source does not explain. It is deliberately not glossed here as a bloodline, a faction or a species, because no public source says which it is. Its tier, its prerequisite and its rank count come from a September 2026 structured tree listing — a strong secondary source rather than a first-hand one, so the edges are reported rather than verified. Its on-screen position, its time cost and any Corruption gate remain unpublished. Its Corruption requirement, rank by rank, comes from a September 2026 Vampirism skill table built against the retail release. Corruption rises only by feeding, so this gate is paced by the run rather than bought at a shrine.
