Why Clear Water God Dungeon?

There are a lot of reasons to clear this dungeon:

Expanded Knowledge - unlocks upgrade that greatly speeds up Runecrafting and Herblore.
Glacia God Armour - gives one of the strongest magic builds, and is required to idle Earth God Dungeon. Also, provides Burning Madness Gloves when up upgrade 10 Glacia God Gloves.
Cloudburst Staff - one of the strongest magic DPS weapons in the game.
Warlock Amulet - reduces overall food expenditure.
Warlock Ring - provides a strong damage boost, and allows access to the Burning Madness Ring.
Glacia Godsword - can be upgraded into the Ultima Godsword.

Drop-rates from this dungeon¹:

Full Armour set: will need 91 clears for a 75% chance, or 192 clears for a 95% chance.
Cloudburst Staff: will need 277 clears for a 75% chance, and 576 clears for a 95% chance.

Standard Guides

Gear

Due to the Combat Triangle, it is recommended to beat the Water God Dungeon with Ranged style, since enemies use Magic and Melee.

Prayers: Sharp Vision & Eagle Eye
Point of Interest: Bandit Hideout

You can expect a clear time of 9 minutes with this setup. Agility and Astrology will greatly increase your clear speeds.

Check your own setup with Can I Idle or Combat Simulator to see if you meet the HP requirements. If you're following this setup exactly, you'll need Level 86 to idle.

Ring of Wealth or Aorpheat's Signet Ring are preferred for the chance of double loot, but you can use Silver Diamond Ring for 1% DR if necessary.

If you have FEZ then use it, but it's not mandatory to have it.

Because later monsters in the dungeon are quite evasive, Ancient Crossbow boosts the clear time by a significant amount because it lowers the enemy's evasion until the end of the fight.

Scaled Shield is important because the poison damages in percentage, meaning that Glacia will suffer. A lot.
With Scaled Shield, you will clear the dungeon at least 10% faster when compared to its unupgraded version, (U) Ancient D-hide Shield.

Use Emerald Bolts to save your Diamonds for Diamond Luck Potion IV.

Use the top two prayers for accuracy or max hit, depending on your situation. Check with Combat Simulator to see which is better for your clear time.

Late-game Idle builds

The remainder of this guide assumes main game only, and does not consider any of the late-game armour and weapons that are available.

The rest of this guide is intended for use after 100+ clears using the build shown above. The goal of this section of the guide is to maximize scrolls and to help farm for any missing items. It is assumed that you are level 99 in all skills with access to all of the weapons and items in the main game, and access to all DR and HP pets. This assumes you are (unless otherwise noted) using a Agility setup optimized for combat, are using your best prayers, your best summoning synergy, and are using Diamond Luck Potions.

Ranged

This build farms around 17 to 18 scrolls/hour, depending on your Astrology bonuses. The Cape of Prat is marginally faster at clearing dungeons than the Maximum Skillcape, but it will also doubles your ammo consumption.

	Shockwave	0%
	Shield of Ranged Power	9%
	Chapeau Noir	0%
	Ranged Hinder Scroll	0%
	Centaur Dragon	0%
Total		48%

Magic

This build uses Fire Surge, Anguish III, and Surge II.

This build farms around 19 to 20 scrolls/hour, depending on your Astrology bonuses. To use this method, you need to have 1090 HP and 57% DR. This is achieved by using Rocky Waters instead of Lake Swim.

The overall time for this build is likely to take longer than setting up ranged because of how many runes you will need. This build relies on the Shield of Magic Power to survive, and also keep a high dps. Overall, it is less effective than the ranged counterpart, and might lower the number of scrolls/hour as a result.

Ancient Relics Guides

On top of no Pets, Astrology or Potions this guide will also assume no Relics.

Much like any other dungeon up to now, Manual Eating will be required.

Melee

Even though this is technically possible, it will require a whole lot of farming.
To be able to do it with melee you will need Level 80 (or Level 70 and Finn, the Cat) as well as farm enough Food Box I from lower dungeons to obtain enough Swordfish for Raft Building.

This dungeon will take roughly 30 minutes to clear with Melee and use approximately 1500 Lobster per clear.

In short, it is highly discouraged to use Melee to attempt Water God Dungeon.

Ranged

Ranged is highly recommended as it takes the most advantage of the Combat Triangle.

Gear

The minimum recommended set is (U) Red D-hide Equipment. (U) Black D-hide Equipment uses around 70 less Lobster per clear.
The clear time for this Dungeon is about 20 minutes.
And will use roughly 630-700 Lobster.

Ancient Crossbow shortens this clear time by roughly 4 minutes.

The Ice Armour can be swapped for Adamant Armour or Rune Armour with little to no impact on the clear speed.
It will slightly lower the Food used.

Red D-hide Equipment and Black D-hide Equipment can be obtained from Spider Forest.
Dragon Crossbow can be obtained from Thieving target Marauder requiring Level 21.
