Background information: Chronozon is one of many bosses that you can kill in Emps-World and can be found on the upper floor of Slayer tower, just past the Abyssal demons. You can get to slayer tower by using a ferocious ring which can be purchased from any slayer master for 150 slayer points, or you can teleport to Falador park and talk to the Ghost captain who will teleport you to Canifis and once you're at Canifis run west and take the right when you approach the fork in the road.
To access slayer tower you need a slayer key which can be picked up on the first floor of slayer tower, just past the Kurask. Thomy recently updated Chronozon to make them a slayer task. Chronozon doesn't require a slayer level, but can only be obtained from Duradel (located in Burthrope). Chronozon gives 5,950 slayer xp. Chronozon is level 347, has 850 hit points, is an aggressive monster, and can hit up to a 30. When fighting Chronozon, he spawns Bouncers that are aggressive and attack with magic.
Gear and Inventory: The best way to kill Chronozon is with mage and range because you're able to trap Chronozon behind a wall which allows him to only attack you with magic. See the picture below on where to trap him. Below you will also see my mage and range setup. I've never killed him with melee, and never will because then he is able to attack with melee and magic and he hits high and often with melee, so keep your distance. Use the magic protection prayer when killing him and you could also use Range or Mage Piety.
Safe spot:
Range:
Mage:If you can't afford a rod a good alternative would be either fire wave or Ice barrage.
