T90 Farming
Following completion of
, you now have access to
, 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 don't want to deal with the hassle of rerolling, or simply want to do them in a specific order, we recommend the following:
- Error creating thumbnail: File missingShockwave - 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
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
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
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
and use it to obtain Ocean Song.
Again:
-
then Ocean Song then Tidal Edge
- Tidal Edge then
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
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
, but there are several skills and items that will make this grind significantly easier, and we would be remiss to not mention them

| 2 | X | ||||
| 3 | Error creating thumbnail: File missing Pipe Climb

No particular reason beyond being the only obstacle that grants any combat benefits. | |||
| 4 | Error creating thumbnail: File missing Coal Stones
|
No negative modifiers, technically saves some food. | |||
| 5 | Error creating thumbnail: File missing Cliff Balance
|
+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 | Error creating thumbnail: File missing Lake Swim
|
+3% damage, +1% DR. Error creating thumbnail: File missing Rocky Waters may help as a first line of defense for surviving if you're mildly undergeared, but will not be considered the default.
| |||
| 7 | Error creating thumbnail: File missing Boulder Trap
|
No negative combat modifiers. | |||
| 8 | Error creating thumbnail: File missing Spike Jump or Error creating thumbnail: File missing Raft Building
|
+5% Chance to Double Items, or extra HP and DR to meet thresholds. Error creating thumbnail: File missing Pipe Crawl will be slightly faster, but the negative to slayer coins hurts, especially for Magic sets using the Error creating thumbnail: File missing Cyclops synergy.
| |||
| 9 | Error creating thumbnail: File missing Ice Jump
|
This obstacle does everything you want it to. | |||
| 10 | Error creating thumbnail: File missing Lava Waterfall Dodge
|
Error creating thumbnail: File missing Ocean Rafting is technically the best dps option. Lava Waterfall Dodge is recommended slightly above it, as you preserve some of your ammo and runes, earn more coins, and have an easier time swapping to skilling to restock.

| P | Error creating thumbnail: File missing Pillar of Combat

Lots of beneficial combat bonuses | |||
Prayer
For Melee, use
and
or the highest level combat style prayers you have available. For Ranged, use
and
or the highest level combat style prayers you have available. For Magic, use
and
or the highest level combat style prayers you have available.
Potions
For all combat styles, use 
Diamond Luck Potions. If you absolutely need the extra damage reduction and can find no other source for it, use 
Damage Reduction Potions
For Ranged, with
, 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
and
For Ranged, use
and
For Magic, use
and
Notably for Magic, using
and
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
, you'll need 48 DR assuming you have
950.
We use Standard Magic as Ancient Magicks have a slower kill rate and higher rune cost.
With Cloudburst Staff, use
or
(reduced rune cost)
With 
Air Imbued Wand or 
Fire Imbued Wand or Ocean Song, use
.
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
- 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.

Shockwave
While the other two weapons are pretty straightforward in terms of gear, the
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 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 Infernal Claw to complete this. Tidal Edge is too slow to reliably survive Rokken's stun without extra work (ie.
), requiring you to make compromises that can negatively impact your kill time.

The Fighter/ FEZ is the best passive/neck setup, even beating out the item doubling from Chapeau Noir.
Slayer Helmet (Master) and Slayer Platebody (Master) positively impact the amount of fragments you receive, and if available, should be used.
For this setup 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). At
, which can be achieved with
and +30 HP from Dragonfire Shield, this method requires 48% Damage Reduction.
To safely use Tidal Edge in this grind, the player's attack speed must be 2.2s during combat, which requires 40% Slayer Area Negation and at least two sources of -0.1s interval. This is typically achieved by wearing the Elder Crown in the passive slot and ownership of
.
To use the 
Ultima Godsword the player must have at least
, 63% DR, and must have 
Wasteful Ring equipped
Check your setup with the Combat Simulator before engaging Rokken.
