The Jack-O'-Skelton is a seasonal boss released during the 2015 Hallowe'en event. He spawns every 15 minutes during the event.
Jack-O'Skelton spawns every 15 minutes in one of a few predesignated places. When he is about to spawn, a server-wide announcement will be shown.
- Jack-O'Skelton has just spawned near Seers' Village
- Directly south-west of Seer's bank.
- Jack-O'Skelton has just spawned near The Wilderness
- Directly in the center of Lava Maze.
- Jack-O'Skelton has just spawned near Lumbridge/Draynor
- Directly west of Lumbridge Castle, by the water well.
His attacks can be predicted by what he says.
- When he says "ENTER DARKNESS":
- The players' screen will go dark for a number of seconds in which time they will take some melee damage, sometimes a considerable amount.
- When he says "Let me lend you a hand!":
- Hands will spawn up from the ground and damage all players within reach. This is an Area of Effect attack.
- When he says "Say hello to my little friends!":
- Jack-O'-Skelton will spawn level 65 Spiderlings. The spiders must be killed first in order for him to take any further damage.
- When he says "Time to mix things up a little!":
- Players will receive a message saying "You hear Jack-O'-Skelton whisper in your ear saying <NAME> should be killed..." If you do not click away during that time, you will attack the named player, which will get you skulled.
Players obtain the following drops upon their first contribution.
|Jack lantern mask||1||Always|
|Living on Borrowed Time||1||Always|
The rarity of the masks is a function of how many masks have already entered the game. Thus, the earlier the player attempted to obtain one after a daily reset, the more successful they would be. Drop rates reset on a daily basis at 00:00 UTC.
|Green h'ween mask||1||Rare|
|Blue h'ween mask||1||Rare|
|Red h'ween mask||1||Rare|
