Thought it was just a pile of rotten meat - till it started to move! – Thibaut from Beauclair
Scurvers are rotfiends' larger cousins. The bodies of these hideous, vaguely humanoid creatures are covered with rotten scraps of flesh, under which lurk even more rotten muscles stretched around a strong, flexible skeleton. Scurvers, which feed on old, rotting corpses, prefer to make their hunting grounds in abandoned torture sites, forgotten graveyards and old battlefields. They are very aggressive and, though they feed on corpses, if they come across a living person they are likely to attack. Thus when wandering near any of the above-mentioned places, one must be especially cautious.
Scurvers usually feed underground, but sometimes, when they catch the scent of a human, they crawl to the surface in a matter of seconds and attack their potential prey.
While fighting them one cannot afford to forget about their special boney spines, razor-sharp protuberances sticking out from their skeletons. When a scurver is near death, the gasses and enzymes gathered within its body cause it to explode, flinging these spines out at great speed, turning them into one last deadly weapon in their arsenal.
To protect oneself against damage from these spines, one should make prodigious use of the Quen Sign.
A scurver fights like a rotfiend except at the very end, when it a final hit will cause it to stop attacking, freezing up as it gets ready to explode, so make sure to use Quen when this happens to protect yourself from the resulting explosion (or get far enough away quickly). On higher difficulties, taking a hit from Scurver's explosion could easily mean certain death.
Scurvers will instantly explode if its health is dropped to zero by powerful enough hits, thus Deadly Precision or anything that randomly inflict Instant Kill on close range are best put aside when facing these Necrophages.
