The serpentine helm is a degradable helmet made at level 52 Crafting by using a chisel on a serpentine visage, giving the player crafting experience. The helmet requires 75 Defense to wear. Its defensive bonuses are comparable to those of the Barrows helmets, without the prayer bonus that Verac's helm offers. It has the second highest strength bonus of all helmets* (*need to verify this)

If a player dies with the helmet in PVP and it is not protected, any scales that were used to charge it will appear on the floor along with the uncharged helmet.

In addition, players can dismantle an uncharged helm to receive 20,000 Zulrah's scales.

The helmet is charged with Zulrah's scales, requiring 11,000 scales to fully charge it. It cannot be equipped if it is uncharged, except when fully degraded while equipped. When fully charged, the helmet will last for 15 hours of combat before returning to its uncharged state.

When uncharging, players will retrieve all the unused scales that were stored in the helm back to their inventory.

The serpentine helm provides two passive effects:

When equipped, the helmet will grant immunity to venom and poison. The opponent has a chance to be inflicted with venom for every successful hit the player does, provided that they are not immune to it. This effect only applies to monsters and does not work on other players. The chances of inflicting venom when the player damages a monster with the helmet equipped are as follows:

1 in 6 chance (16.7%) if using a non-poisoned melee weapon (this includes melee hits with the Toxic staff of the dead, since it alone can only apply venom with spells). 1 in 2 chance (50%) if using poisoned weapons (abyssal tentacle counts). 100% chance if using the toxic blowpipe, trident of the swamp, or damaging spells with the toxic staff of the dead.

The player can use mutagens dropped by Zulrah to recolor the serpentine helm into one of its two color variants: using a magma mutagen creates a magma helm, and using a tanzanite mutagen creates a tanzanite helm. These variants do not apply any stat changes and are purely cosmetic. The way to obtain the mutagens is either by killing Zulrah itself(the only way for ironman), or players.
