Smoke nihil

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

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

The smoke nihil, like the other nihil in the arena, runs across the halls and into holes in the wall, causing damage to and draining the stats of any players that stand in its way. It always runs west, appearing from a different hole each time, until the player attacks it and draws its attention, at which point it solely focuses on using magic. The smoke nihil has a very high defence, so players are recommended to bring weapons that are at least level 70. Like the other nihils, the smoke nihil has a special attack, which gives a "hiss" warning before its use. When activated, the nihil attempt to choke a player using a smoke barrage. This special attack does not deal any direct damage damage to the player. Instead, it reduces all combat stats by 5 every tick. Smoke-resisting headwear, such as a slayer helmet or a facemask, will not prevent this attack's effects from occurring; however, it can be avoided entirely by running at least two steps away from the spot the player was when the nihil hissed.

After the quest, the nihils may be fought for their drops. They are aggressive unless the Shard of Zaros is equipped.
