The Dagannoth Kings can be a decent money making method. They drop dragon hatchets, berserker rings, archers' rings, warrior rings, seers' rings, and other drops relatively often. Using a pack yak will further increase your profit as you will be able to bank the dagannoth bones and dagannoth hides you receive. Wearing Fremennik boots 4 will increase profit as the bones will become noted, and with a pack yak you can bank the hides.
The Kings reside on the sixth floor (the deepest) in Waterbirth Island Dungeon.
- Dagannoth Prime is the deadliest Dagannoth King. He is immune to melee and magic attacks, so he must be killed with ranged. Despite this, his defence against ranged is still relatively high. Prime hits hard and is usually the most dangerous out of all the Kings. Stay in the north-eastern corner of the room and the other Kings won't notice you attacking Prime.
- Dagannoth Rex uses melee, hitting multiple players at a time if they stand beside each other. He is immune against melee and ranged attacks, but is extremely weak to magic. Rex can be easily safespotted in many spots on the south-east side of the "island".
- Dagannoth Supreme uses ranged attacks. He is immune to magic and ranged. Supreme's attack hits multiple players if they are close to each other.
- Spinolyps inhabit the moat surrounding the Dagannoth Kings' island. They are very weak and have 1000 life points. They do not hit very high or very accurately, but their ranged attacks poison you and their magic attacks drain ten prayer points if they hit. The poison damage starts at 68 so it may be worth bringing an antipoison potion. They can be used to stall adrenaline efficiently or build more of it while waiting for the Kings to respawn. Use of the Sacrifice ability can also prove useful, as it will usually kill them in one hit and often provides a free 1000 life point heal.
An instance can be created for 150,000 coins, unless the creator has unlocked the Instance Cost perk obtained via Reaper points, reducing it to 112,000 coins for one hour.
This setup only uses Ranged and Magic combat, and is very easy to do solo. Stay in the eastern side of the room to avoid Supreme.
Body and leg switches are advised, however not needed. Hybrid armour such as warpriest armour or void equipment can be used. Make sure you use Telekinetic Grab on any desired loots Prime drops to avoid being hit by Supreme. It is still advised to carry some melee weapons in the event that Supreme is alerted to your presence. Players should either remove Ricochet and Bombardment from their ranged bars as they may bounce onto Supreme if he is too close to Prime.
Using this method, you should have the following abilities in your ability bars. Switch between two bars.
- Magic: Impact, Combust. Wild Magic, Asphyxiate
- Ranged: Binding Shot, Snipe, Rapid Fire, Fragmentation Shot, Deadshot/Death's Swiftness
- Constitution: Guthix's Blessing, Regenerate or Ice Asylum
- Defence: Debilitate and/or Devotion to lower Prime's damage
Magic ability bar (2H):
This setup only uses Magic, and is mostly used because Rex is the easiest out of all the Kings, due to being able to be safespotted.
As the Dagannoth Kings boss instance starts empty for about 10 seconds, it can be used to sneak into the south-east safespot corner without drawing aggression from Prime and Supreme.
If you are going to attempt solo tribridding for the first time it's recommended to have spare money and/or a friend to bless your grave in the event of death.
A slayer task will help with tribridding to deal more damage and gain extra accuracy. While on a task, using overloads, Soul Split, Turmoil curses and high level gear; it is possible to obtain over one hundred Dagannoth Kings kills per hour.
The Demon horn necklace paired with a Bonecrusher is an effective setup, as the buried bones will allow prayers to last forever if the Kings are killed at a reasonable rate. This does come at the cost of the bones themselves, as they are worth a decent amount at the Grand Exchange. The necklace will not work if the player is wearing Fremennik sea boots 4, as it will note the bones and prevent them from being crushed.
When using an instance, the 'fast' setting is usually enough. "Fastest" should only be used if the player is extremely confident in their skills and has tier 90 weapons on all three combat styles, as it will be near-impossible to keep up with tier 80 or 85 weaponry.
Hybrid armour is advised to save inventory space, as bringing three different types of armours would take away space that could have been used for restoration potions, pouches and food.
- Melee: Slice, Dismember, Slaughter, Assault, Destroy, Berserk, Debilitate, Punish, Backhand or Kick
- Magic: Impact, Combust, Metamorphosis, Sunshine, Sonic Wave, Wrack, Wild Magic
- Ranged: Debilitate, Binding Shot, Rapid Fire, Bombardment, Fragmentation Shot, Snipe, Death's swiftness
Magic ability bar (2H):
When fighting with these abilities, make sure you have the right gears. If you have at least least tier 90+ weaponry (seismics, ascensions, drygores or noxious weaponry), the King that you are killing which is weak to that weapon should die fairly easily without having much difficulty. However, if one of these weapons are tier 80, you will want to follow below to counter them quickly before another King spawns while you are attacking the current one.
- If you lack melee, but have magic/ranged: Use Berserk against Supreme.
- If you lack ranged, but have melee/mage: Use Death's Swiftness against Prime.
- If you lack magic, but have melee/ranged: Use Sunshine against Rex.
If you have level 80 dual chaotic weapons, using Berserk is optional against Supreme as the kill rate with chaotics is slightly lower but enough to prevent another King from interfering with the fight.
Familiars can be really useful while doing Dagannoth Kings. The pack yak is an excellent familiar, as you can bank bones (if you have not done the elite Fremennik Tasks), hides, and other important drops, in addition to carrying supplies to extend your trip. When the pack yak expires, summon a unicorn stallion if you need to.
How to kill the Kings
The Kings reside in a circular islet, with each King having their own "private" zone and a zone where they all meet each other. When there are all three Kings in the arena, try to stay as far as you can from the middle because it can be very dangerous to be hit by all three of them at once. Prayers only will block 50% of one of their attacks, while the other two can hit for 100%. If you are spotted by one of the Kings, they will keep attacking you until you leave by any means or kill them. The only way to get them off you is by them getting distracted by another player or dying.
- When killing Dagannoth Rex, lure him away from the other two kings. He will home in on you very quickly, and you can either stun safespot him or just use the ragged edges of the islet to safespot him.
- When killing Dagannoth Prime, stay on his side of the islet (north-east) with a ranged weapon. If you get too close to him, Supreme will come in and interrupt the fight, which can be problematic when you are low on food. Soul Split is not advised unless the player is using Devotion with Protect/Deflect magic, as Prime hits the hardest out of the three Kings.
- When killing Dagannoth Supreme, lure him to the ladder, the top or the sides (depending on which way he moves when you're under him), so if one of the other Kings spawn, you decrease your chances of being spotted by them. If you fail to kill them efficiently, let the three respawn and target Rex first. This will decrease the chance of being attacked by another King while you are busy dealing with one of them.
When starting the kill, you have a few options to deal with them:
- If Supreme is close to the ladder, kill him since Rex doesn't tend to notice you yet.
- If they are near the middle, sneak around the corners of the islet until you are on Rex's side, then kill him. This is mostly luck-based, but if it is pulled off, the player can start killing Rex without being noticed by Supreme.
- Simply attack them. This is the most dangerous, but if Rex is alive quickly use a magic stun or bind him since he is not stun immune. Make sure he isn't directly under Supreme, otherwise the stun will go to waste. If you can use Debilitate or Devotion, immediately use it on the King you're focused on and use the prayers against the one you aren't to avoid unnecessary damage.
- When joining an instance, quickly run north-east and kill Prime when he spawns then run south-east and kill Rex and finally run west and kill Supreme. This leaves you in a good position to kill the three kings as they spawn and you should only have to deal with 1 king at a time. To quickly kill Prime when he spawns after killing Supreme, get into melee range of him and use Death's Swiftness and before that ends you should have enough adrenaline to then use Rapid Fire which will kill Prime very quickly.
