The corrupted slayer helmet is a tier 85 slayer helmet requiring level 70 Defence to equip (even though level 80 Defence is required to create the helmet). It is made by upgrading a mighty slayer helmet for 1,000 Slayer points and a corrupted gem at any Slayer Master. It has the following effects from its components:
It provides a 14.5% boost[1] in damage and accuracy to Melee, Ranged, and Magic attacks against the player's current Slayer assignment; a 0.5% increase from the Mighty slayer helmet
It provides a 5% bonus chance to catching souls in ushabtis
The slayer helmet is an all-class item, which means its armour stat is used in full when defending against any style. It has the same base stats as a Refined Anima Core helm of Sliske. It can also be used as an enchanted gem.
For 500 Slayer points (or 50 Slayer points any time after first purchased), players can learn how to fuse rings of slaying and ferocious rings to full slayer helmets, gaining some of the benefits of both - transports, ferocious ring 4% damage boost in Kuradal's Dungeon but without the ring of life property
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, Dilwyn, or Wafa, 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:
There currently bug in defense requirement for Corrupted Slayer helmet which requires 70 defense to buy, but players attempting to buy it from Slayer Reward Shop,it will not allow you to buy unless you have level 80 defense requirement. This bug has yet to be fixed.
