The blue full slayer helmet is a level 20 slayer helmet with bonuses equivalent to a hybrid iron full helm. It is made by combining a focus sight, hexcrest and slayer helmet (which must be uncharged beforehand) by using one on any of the others. This requires 55 Crafting and completion of Smoking Kills. It has the following effects from its components:
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.
For 500 Slayer points (or 50 Slayer points any time after first purchased), players can upgrade the helmet to fuse rings of slaying and ferocious rings, gaining some of the benefits of both.
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 are:
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.
