When using Ice Barrage and a cannon, smoke devils can provide high Slayer experience rates of up to 180,000 per hour, depending on how well the player can not lose any time attacking during grouping them and collecting their loot, but a rate of 120,000 is more realistic for a player paying only moderate attention. Smoke devils reside in a multi-combat area, so players can burst / barrage or use chinchompas on them, though only the former is particularly effective. Smoke devils, are a slayer monster requiring 93 Slayer to kill. Given the fact that the smoke devil chamber is very large, bringing a cannon is recommended to get their attention.
