Slayer helmet

Slayer Helmet
The Slayer Helmet is a piece of useful equipment when doing Slayer tasks due to the fact that some tasks require protection from monsters. It nullifies the effects of  Slayer NPC's, and removes the need to bring multiple items for Slayer tasks. It also gives a 15% bonus to Melee damage (bonus only applies on your Slayer task). . You can get a Slayer Helmet from the Slayer shop for 1,7M Coins.

Trivia
Some players only wear the Slayer Helmet because of it's "stylish" looks.
