The slayer helmet is an All-class item, which means its armour stat is used in full when defending against any style. It can also be used as an enchanted gem.
It has been enchanted to hold summoning scrolls by Pikkupstix. Up to 900 combat scrolls can be stored in it by using them on the helmet. It can be unenchanted by talking to Pikkupstix again.
The helm can hold a maximum of 30 ferocious ring charges and 40 ring of slaying charges, made by using the rings on the helmet and requiring 60 Crafting. For example, using a ferocious ring with 5 charges on a fused slayer helmet that has 27 charges ferocious ring charges already will result in 3 charges being added to the helmet and 2 charges remaining on the ring. Fused slayer helmets allow using the teleports from the ferocious ring and the ring of slaying. Additionally, helmets fused with ferocious rings give the 4% damage boost in Kuradal's Dungeon. However, they do not provide ring of life-style teleport that the ferocious ring does. Fused slayer helmets can also be recharged with co-op points.
For 4000 loyalty points, players can buy the ability to change the colour of their slayer helmet, and this works for all variations of slayer helmets except the most basic slayer helmet. By using the helmet on Xuan or Dilwyn, it can be recoloured to the colours blue, yellow, red, and green. Recolouring the full slayer helmet also changes the colour of the backplate to pastel pink. This ability cannot be refunded, but once bought, players can change the colour of their helmet as many times as they like. The pink backplate can only be removed/changed by reverting to the original colour. The four versions are:
