The Plague King
“A withered king in a twisted iron crown, robes weeping sickly green rot. The air around him turns the stomach. He guards the road to worse things still.”
Fighting it
- It swings back once every 3 of your combat inputs, whether your attack hit or not.
- A kill is worth about 28,800 Melee or Ranged XP, or 39,600 Magic XP, plus about 9,612 Hitpoints XP. XP is paid per point of damage and shared out by your stance (a stance that sends half to Defence pays it at Defence's rate of 8). A finishing blow that overshoots adds a little more; poison and Vengeance damage pay nothing; XP bonuses from gear and food add on top.
- Its hits roll from 0 to 31 (half its Strength, plus one). The prayer Spellguard blocks them completely.
- Soft or unarmoured: Melee and Ranged tear in; Magic only lands normally.
- Putrid: each of its hits that does damage has a 30% chance to poison you. Plague-touched food (auto-eaten in combat) or an antipoison potion keeps it off, and putrid monsters can't be poisoned themselves.
Slayer
- A boss task from Vex, once you have the Boss Tasks unlock.
- On task, each kill gives 14,400 Slayer XP (4× its hitpoints).
Journal tasks: kill 1 for the Warrior's Journal (Hard).
Drops
Every row rolls on its own, so one kill can drop several things. Drops go straight to your bank (a pet goes straight onto you). Gear and potions that raise your rare find chance don't change these odds.

After a kill the next one appears 2.5 seconds later. Dying costs nothing but time: a 15-second wait before you can fight again. The Agility perks Hot Pursuit and Second Wind shorten both (see Combat).
