Slayer on SpawnPvP includes regular and Wilderness tasks, superiors, and a token shop. Twisted banshees count for the Banshee task. Coin caskets on a Slayer task pay Wilderness slayer tokens.
On a task kill
1. Superiors
1 in 200
A superior can spawn on a regular Slayer task kill that counts for your task.
1 in 150
Wilderness Slayer task kills use the better 1 in 150 roll.
5× XP
A superior pays 5× the base Slayer XP, despawns after 3 minutes, and can drop an Imbued heart at 1 in 200. It spawns for the killer only.
Twisted banshee kills count for the Banshee task and can spawn a Screaming twisted banshee. Other mapped superiors include cave crawlers, banshees, rockslugs, cockatrices, pyrefiends, basilisks, infernal mages, bloodvelds, jellies, dust devils, kurasks, gargoyles, nechryael, abyssal demons, dark beasts, crawling hands, deviant spectres and smoke devils.
Some superiors are not spawnable here: there is no Aberrant spectre, Cave horror or wilderness Greater nechryael definition, and Deviant spectres have no Slayer task so Repugnant spectres cannot spawn.
Regular and boss
2. Tasks
Tormented Demon, Doom of Mokhaiotl, Great Olm, Royal Titans (Eldric counts) and Yama are regular tasks at Slayer 93–99 and also boss tasks. A slayer helm applies to Eldric, Olm’s claws and Doom’s other forms. A claw kill does not finish an Olm task.
Coin caskets only drop on a task kill. Open one on a Slayer task and it pays Wilderness slayer tokens; otherwise it pays PvP task tokens. Helm recolours still give the on-task bonus when worn.
Wilderness slayer tokens
3. Shops
The Wilderness slayer shop is for everyone except iron men. Iron men use a separate shop without revenant or demonbane weapons, Nightmare staff or coloured helmets. Shared prices include Dragon crossbow 3,000, Dragon hunter crossbow 5,000, Imbued heart 3,210 and Saturated heart 4,500. Coloured imbued slayer helms are 1,000 tokens each (Tzkal 2,000) in the normal shop.
TzKal slayer helmet needs 250 wilderness slayer tasks plus 1,000 kills each of Vet'ion, Venenatis and Callisto. Full Iron Man prices are on the Iron Man guide.
