Dominion mines are a reward that can be purchased after killing 400 bosses and finishing all special challenges, with the exception of Sunfreet, within the Dominion Tower. Each mine costs 1000 coins, with 10 mines purchased at a time from the Strange face.

Only two dominion mines can be placed per minute, although if picked up, players can immediately place them again. It is displayed as two 1-minute buffs for the two mines separately, allowing you to track when you can place a mine and when you can place another. If there is a valid target in range, starting from the moment you click "deploy" it takes about 5 seconds for a mine to go off. If not triggered, a mine lasts for 1 minute before despawning, causing it be lost.

A dominion mine exploding on a dummy, which has a damage cap twice as high as normal.

These mines always hit 20% of the monster's maximum life points, up to 10,000 melee damage. They are always single-target, hitting the mob within a 7x7 area. They prioritise the closest target, not the target the player is attacking. Dominion mines can only be triggered by NPCs of level 138 combat or less, making most bosses immune to them. They are useful against monsters with high life points, such as rune dragons. Monsters will not become aggressive when hit by a mine. Note that mines can only be used to damage the target, the killing blow must be dealt by the player. Mines placed on an NPC with life points lower than the damage the mine would deal will not detonate.

Soul Split heals from the damage Dominion mines deal.

Curse and Vulnerability cast on the target would cause Dominion mines to deal 5%/10% more damage (21%/22% maximum lifepoints).

Dragon Slayer (perk) (+7% damage) will raise the damage from 20% to 21.4% of maximum lifepoints against dragons.

Shattered Worlds mobs only take 20 damage from the mines. They cannot be used inside the Dominion Tower itself, nor in the Sunken Pyramid.

Usage in boss encounters[edit | edit source]

  • Against black crystals when fighting Seiryu the Azure Serpent due to their high life points and the limited time allowed to damage them.
  • Against Black hands when fighting Black stone dragon due to their high life points and defence.
  • Against Volatile rootlings when fighting Solak - in duo mode, two mines can instantly destroy a rootling as soon as they spawn. In group mode, more can be placed after the initial two mines that were placed before the fight began detonate.
  • Against Gregorovic, who randomly changes combat levels between 1 and 1000, occasionally allowing him to become vulnerable to Dominion mines.
  • Against the Abomination after the quest Hero's Welcome, which has very high defence, making mines useful against it.
  • Against Nex: Angel of Death - before starting place the mines in all four quadrants where the blood reavers will spawn. This allows you to kill the reaver quick and continue phasing Nex.
  • Against Fragments when fighting The Ambassador. Best used if the beam is about to catch up to your current fragment, or as part of your regular damage rotation as you clear fragments.

Usage in Slayer[edit | edit source]

Some monsters fit well within the parameters of having a combat level of 138 or lower as well as a large life point pool. These monsters are susceptible to taking the maximum or close to maximum amount of damage from dominion mines, which can help speed up certain Slayer tasks.

Trivia[edit | edit source]

  • While river trolls and rock golems in the Enchanted Valley have no combat level, they are affected normally by Dominion mines. The 1-life point version of the rabbit found in the area would trigger the mine, but take no damage.
