Blood nihil

The blood nihil is fought during the Fate of the Gods quest alongside the smoke nihil, the shadow nihil and the ice nihil.

The blood nihil is a member of the nihil race, created by Zaros during his testing of genetic manipulation. By its examine, the blood nihil was likely created by weaving the essence of a vampyre.

The blood nihil, like the other nihil in the arena, run across the halls and into holes in the wall, inflicting damage and a 100 damage Slaughter to any players that stand in its way. It always runs east, appearing from a different hole each time, until the player attacks it and draws its attention, at which point it solely focuses on using melee. The blood nihil has a very high defence, so players are recommended to bring weapons that are at least level 70. Like the other nihils, it has a special attack, which it signifies by emitting a "hiss" warning. When activated, it summons a siphon shield that heals it when attacked, similarly to Nex during her blood phase, though it does not attack or move for the duration of the effect. It is recommended not to attack the blood nihil while it under the effect, or it can heal large amounts and prolong the fight. The blood nihil makes a sucking sound while using its special attack. Aside from its special attack, it also siphons any damage it takes to heal other nihil by the same amount. For example, inflicting 500 damage on it heals other nihil by 500 lp each. For this reason, it is recommended to kill this nihil after the others are dead.

After the quest, the nihils may be fought for their drops. They are aggressive unless the Shard of Zaros is equipped. Their special ability does not heal other nihils.

Trivia

 * Blood nihil take damage from bleeds, rather than healing from them, similar to Cruor. It is unknown if this is a glitch or not.
 * A blood nihil's healing ability is twice as long as Nex's.
