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 had been enchanted to hold summoning scrolls by Pikkupstix. Up to 900 combat scrolls could be stored in it by using them on the helmet. It could be unenchanted by talking to Pikkupstix again.
The helm could hold a maximum of 20 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 17 charges ferocious ring charges already resulted 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 Slayer points.
For 4,000 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 of this helm were:
The full slayer helmet can be upgraded to the tier 1 upgraded helmet, the reinforced slayer helmet, for 100 Slayer points, giving it better stats and a higher requirement to wear. If a player has upgraded the helmet at least once before but disassembled or lost it, it can be re-upgraded for only 10 Slayer points.
