Dark Waters/Guide
This page was last updated for (v1.1). |
T90 Farming
Following completion of Into the Mist, you now have access to
Dark Waters, the penultimate slayer area. These 3 mobs drop fragments for the T90 weapons, the highest level, and often most powerful, weapons in the game that are extremely helpful in completing the following slayer area, as well as the Impending Darkness Event. These are extremely long grinds, and require quite a bit of preparation. Each weapon requires 100 fragments, and the fragments have a 2% drop rate. That's 5,000 kills on average.
We recommend acquiring them while fighting each monster as a slayer task, this will require you to turn OFF auto-slayer, and will encourage semi-frequent check-ins. Doing these on task will increase your damage dealt to them from various buffs, namely Slayer Skillcape. This will make the order you obtain the final weapons in effectively random, but if you want to do them in a specific order, we recommend the following:
Shockwave - Made from
Shockwave Fragment, dropped by
Rokken
Ocean Song - Made from
Ocean Song Fragment, dropped by
Ku-tul
Tidal Edge - Made from
Tidal Edge Fragment, dropped by
Umbora
Additionally, you should also acquire the pet Otto whilst doing this grind, if you do not, continue farming whichever mob you kill the fastest on or off task until you get it.
Item fragments are very rare drops, and you should attempt to sneak in as much item doubling into your gear as possible. Using Combat Sim to measure your Drops/hr with no deaths is highly recommended. It can make the difference in literal days of grinding.
Order
The order you obtain these items in is not particularly important.
While it may seem that using these weapons to farm the other weapons would be beneficial, this is not the case due to the relatively weak power level of Tidal Edge and
Ocean Song compared to other available weapons. The only suggestion here is to obtain
Shockwave and use it to obtain
Ocean Song
The common orders are:
- Shockwave then
Ocean Song then
Tidal Edge
- Tidal Edge then
Shockwave then
Ocean Song
Between those two, the required time is roughly equal.
Many people combine the grinding of these weapons with the grind for the master slayer gear. An added benefit is the increased damage given by the Slayer Skillcape and buffs from
Astrology while fighting slayer tasks. Another benefit is the ability to buy prayer points,
Light Runes, and Food at a profit with the use of
Generous Resupply.
Requirements
There are very few hard requirements beyond the ability to survive and the entry requirement of Slayer Level 90, but there are several skills and items that will make this grind significantly easier, and we would be remiss to not mention them

Below are some gear suggestions. Depending on what Prayer,
Potions, and
Agility buffs you use or have access to, your optimal gear can change.

3 | No particular reason beyond being the only obstacle that grants any combat benefits. | ||||
4 | No negative modifiers, technically saves some food. | ||||
5 | +20 hp. This does make your prayers cost more, but as you're buying your prayer points anyways, the cost increase isn't quite as painful. | ||||
6 | +3% damage, +1% DR. | ||||

Prayer
For Melee, use Battleheart and
Piety or the highest level combat style prayers you have available.
For Ranged, use Battleheart and
Rigour or the highest level combat style prayers you have available.
For Magic, use Battleheart and
Augury or the highest level combat style prayers you have available.
Potions
For all combat styles, use Diamond Luck Potions
For Ranged, with Shockwave, it is sometimes possible that
Ranged Strength Potion IV is stronger than Diamond Luck Potions. This should never be done without checking Combat Sim for yourself, and should never be done unless the potion is specifically
Ranged Strength Potion IV, and not any lower mastery.
Summoning
For Melee, use Dragon and
Minotaur
For Ranged, use Dragon and
Centaur
For Magic, use Dragon and
Witch
Notably for Magic, using Cyclops and
Witch tablets will earn you significantly more coins at a fairly minimal loss of kills per hour. This is most obvious with
Cloudburst Staff.
Tidal Edge
To be able to idle Umbora with
Magic, you'll need 47 DR assuming you have 1000 HP.
Umbora can be killed with Normal Magic if you have a
Cloudburst Staff or an
Ocean Song, or with Ancient Magicks at a much slower rate. Note that Cloudburst is by far the fastest method, even if you have to squeeze in extra DR from
Guardian Ring or
Prayer
With Cloudburst Staff, use
Water Surge or
Water Wave (reduced rune cost),
Anguish III, and
Fury II.
With Ocean Song, use
Fire Surge,
Anguish III, and
Surge II.
With an Air Imbued Wand or a
Fire Imbued Wand, use
Gust or
Incinerate.
Use of Combination Runes is highly recommended for all methods.

Slayer Wizard Hat (Master) and
Slayer Wizard Robes (Master) will kill you if used with
Cloudburst Staff and the normal build above. If all you care about is fragments, it is possible to equip a build with Master Slayer armor that is approximately 4% faster than the above recommended build. This is accomplished by equipping
Slayer Wizard Hat (Master),
Slayer Wizard Robes (Master),
Skull Cape AND
Rocky Waters - all 3 pieces of equipment must be worn to outpace Glacia armor, and the agility course keeps you from dying. You need 1090 HP and 44 DR.
Ocean Song
To be able to idle Ku-tul with
Ranged, you'll need 48 DR assuming you have 1,000 HP.
To most efficiently kill Ku-tul you'll use one of
Shockwave,
Slayer's Crossbow or a
Stormsnap. Use of
Jadestone Bolts is recommended,
Emerald Bolts are not recommended as jadestone bolts should be plentiful enough at this point in progression.

40% slayer area reduction increases your dps against Ku-tul, and therefore, unless it will lead to your untimely demise, at least a
Slayer Cowl (Elite) should be used.
Slayer Cowl (Master) and
Slayer Leather Body (Master) positively impact the amount of fragments you receive, and if available, should be used.
Shockwave
While the other two weapons are pretty straightforward in terms of gear, the Shockwave is not.
Rokken is by far the most dangerous and is both willing, and able to kill you if you are not extremely careful in your setup. This monster is able to buff itself to an attack speed of 2.2s, and is able to stun you, which massively increases its damage against you. Your goal here is either to be able to survive the increased stun damage, or to never actually take the stun damage by having an equivalent or faster attack speed than the monster.
You need to use Melee for this grind, and as said before, it is highly recommended that you use an Infernal Claw to complete this.
Tidal Edge is too slow to reliably survive Rokken's stun without significant extra work, requiring you to put on more DR that will massively affect your kill time. Assuming you were able to use the exact same setup with no
Astrology buffs,
Infernal Claw is only 1-2% slower than
Tidal Edge. Adding buffs from
Astrology, adding the additional DR or attack interval reduction required for Tidal Edge, and using summoning combat familiars invert this difference and make Tidal Edge up to 20% slower with no tangible benefit.

The Fighter/
FEZ is the best passive/neck setup, even beating out the item doubling from
Chapeau Noir. Note that wearing
FEZ is required to wear Master Slayer armor.
One major note is that the Ring of Blade Echoes is marginally faster for fragments/h than all other rings, however, due to its interaction of significantly increasing your use of consumables like Prayer Points and Potions, it is lower on the rankings.
Slayer Helmet (Master) and
Slayer Platebody (Master) positively impact the amount of fragments you receive, and if available, should be used.
For this set-up to work safely without risk of death, the player's attack interval while in combat with this enemy must be less than or equal to 2.2 seconds, as this means the player is quick enough to avoid taking extra damage when Rokken attacks with the Shockwave special attack. To achieve this, we use a weapon that has a base 2.2s interval, and gather 40% total slayer area negation through
Slayer Skillcape and
Slayer Helmet (Elite).
Check your setup with the Combat Simulator before engaging Rokken.
At 1,000 HP, which can be achieved with Level 97 and +30 HP from
Dragonfire Shield, this method requires 48% Damage Reduction.
