DISCLAIMER
None of these weapons are actually required to beat Impending Darkness Event.

If you own Throne of the Herald Expansion, Ocean Song and Tidal Edge will be easily replaced by weapons such as Heated Fury 2H Hammer and any of the Runecrafting Wands.

Shockwave doesn't have a direct easy upgrade in Throne of the Herald Expansion but if you own Atlas of Discovery Expansion then Engulfing Vortex Longbow is a much better weapon that doesn't really get replaced unless you have Merman Pendant or at level 120 by Feather Storm Crossbow.

All drop estimates were done without any Pets, Astrology or Pillar of Combat. Having these will significantly increase your drops per hour.

Dark Water Level 90 Weapon 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 Level 90 weapons, the highest level, and often most powerful, weapons in the base 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. This will make the order you obtain the final weapons in effectively random, but if you don't want to deal with the hassle of rerolling, or simply 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, (the average amount of kills required to obtain all of the drops with no doubling is 5000 per monster), and it should be noted that there is a Township Task that requires the player to Kill 5,000 Ku-tul, 5,000 Umbora, and 5,000 Rokken, therefore Item Doubling is not as important for this specific grind as it might otherwise be.

Additionally, there is another Township Task that requires 1 of each Fragment and rewards 3 of each Fragment, to shorten the grind a little.

After completing the task, or if you simply want your first copies as soon as possible, you should attempt to sneak in as much item doubling into your gear as possible. Using the Combat Simulator to measure your Drops/hr with no deaths is highly recommended.

Order

The order you obtain these items in is not particularly important.

Using the weapons obtained from killing each monster makes sense, unfortunately, they have historically not always the best available options, however a balance patch in Melvor Idle 1.1 has changed the meta an amount, and this guide will strive to stay updated. For now, the only recommended order is to obtain Shockwave and use it to obtain Ocean Song.

Again:

- 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

Suggestion	Benefit
Level 90 - Level 95	Less need for DR
Level 99	Pillar of Combat
Level 90	Dragon Synergies
Level 90
Slayer Helmet (Elite) Slayer Platebody (Elite)	15% Flat Slayer Area Effect Negation

Tidal Edge

To be able to idle Umbora with Magic, you'll need 48 DR assuming you have 950 Hitpoints.

We use Standard Magic as Ancient Magicks have a slower kill rate and higher rune cost.

With Cloudburst Staff, use Water Surge or Water Wave (reduced rune cost)

With Air Imbued Wand or Fire Imbued Wand or Ocean Song, use Fire Surge.

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 Raft Building - all 3 pieces of equipment must be worn to outpace Glacia armor, and the agility course keeps you from dying. You need 1050 HP and 45 DR.

Ocean Song

Equipment

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 easily obtainable at this point in progression from Hunting Greater Dragon.

Prayers: Eagle Eye & Sharp Vision
Potion: Ranged Assistance Potion IV
Point of Interest: Bandit Hideout

Idle HP, DR and Drops/h

To be able to idle Ku-tul with Ranged, you'll need:

HP	DR	Selected Gear From Equipment Table	Drops per Hour
970	49	Shockwave, Scaled Shield, Slayer Cowl (Elite), Slayer Leather Body (Elite), FEZ	2.4
970	50	Shockwave, Scaled Shield, Slayer Cowl (Master), Slayer Leather Body (Master), Deadeye Amulet	3.1
970	49	Slayer's Crossbow, Scaled Shield, Slayer Cowl (Elite), Slayer Leather Body (Elite), FEZ	1.85
970	50	Slayer's Crossbow, Scaled Shield, Slayer Cowl (Master), Slayer Leather Body (Master), Deadeye Amulet	2.3
1040	47	Stormsnap, Slayer Cowl (Master), Slayer Leather Body (Master), FEZ	2.2

For Stormsnap you will need to swap Agility Obstacle 6 to Rocky Waters and Prayer from Eagle Eye to Stone Skin.

Shockwave

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 increases its damage against you by 30%. 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's fastest speed.

You need to use Melee for this grind, it is highly recommended that you use an Tidal Edge, Infernal Claw or Ultima Godsword to complete this.

Equipment

This Equipment should work at Level 95 (990 HP) with 56% DR.

Prayers: Stone Skin & Battleheart (Requires Level 95 otherwise use Chivalry)
Potion: Diamond Luck Potion > Melee Accuracy Potion IV or Melee Strength Potion IV
Point of Interest: The Molten Peak ( Dark Waters Lowers our Slayer Negation so ends up with less kills)
