Slayer Coins
Slayer Coins are earned by completing 
Slayer Tasks. A guide explaining Slayer Task mechanics can be found here. Monsters killed for Slayer Tasks earn Slayer Coins and Slayer experience points equal to 10% of the slain monster's hitpoints. Note that Slayer Tasks are the only way to earn Slayer Coins, and killing monsters in a Slayer area that aren't the player's current Slayer Task will not earn them Slayer Coins.
