Dragonkin Laboratory (Ranged Advanced)

Introduction

The second Elite Dungeon, the Dragonkin Laboratory, is a relatively straightforward encounter. The encounter is useful for anyone wanting to learn how to deal with large mobs as well as bosses and combines aspects of single target and AoE damage.

The three bosses of the Laboratory drop the Greater Flurry, Greater Fury and Greater Barge codices in the order that they appear.

Each solo run of ED2 is worth coins 12,759,816 in uniques.

General Notes

⬥ It's recommended to set your anti-spam delay for your surgemobile to 1 via the Lectern at Anachronia.

⬥ You can surgemobile or bdmobile a tick before each gate unlocks to save a tick on every entry.

LotD Luck of the Dwarves will not improve the number of energies dropped, nor the drop rate for any codex.

⬥ The guide assumes knowledge of bosses and ranged rotations. Visit #ED2 Basic Guide or #Ranged DPM Advice as needed.

Presets and Relics

Preset Suggestions
Ranged

Astellarn, the First Celestial

The first encounter of the Laboratory, this fight heavily utilises punishing area-of-effect mechanics but is still very straightforward and easy to master with some practice. Additionally, she drops the gflurry greatercodex

Example Rotation

Start of fight: gricorapidsgb eofspecsnap to prephase

After Pulsar spawn: grico / mds → equip deathsporearrows + build to 100% and 5 deathsporearrows stacks on Pulsar and Astellarn → incend → equip jasdragonbanearrow → get 3+ perfectequilibrium stacks with basics → ecb eofspec when neutron star spawns → lure star into black hole → dragonslayer + bolg specsgb eofspecgricosnaprapid if needed → divemobile diagonally to the next room

Note: 1st sgb eofspec must be cast when Astellarn is >200k HP so you may need to cancel rapid early.

Example kill (Astellarn):

Verak Lith

The second encounter of the Laboratory. Verak Lith's attack rotation is predictable, but deals consistent moderately high damage. Therefore, it is recommended to learn the mechanics properly to avoid any unnecessary deaths. Additionally, he drops the gfury greatercodex

He always melees the player when in melee distance and always uses mage otherwise. The auto attacks hit quite hard with the mage ones being desynced visually, so it is important to not mess up too many prayer flicks here.

Example Rotation

ecb eofspec + dive + surge into md of Verak → (tc) + ingen + smokecloud + gricodragonslayer + bolg specsgb eofspeclimitless + snaprapidgrico → equip deathsporearrows + mds + place dommine for Spire → divert on Spire → finish off Spire with basics then use basics on Verak to 100% and 5 deathsporearrows stacks → gdeathsswift → equip jasdragonbanearrow + ecb eofspec + adrenrenewalbolg specsgb eofspecgricosnapmdsrapidgricomdsshadowtendbolg specmdsdivert the Spire → kill Spire with basics → dragonslayer + rapidsgb eofspecsnap → finish off with basics → surgemobile back towards the bridge

Note: Save disrupt for bomb, if following the rotation above you will use it right before the first rapid post adrenrenewal

Note: soulsplit flick properly is very important in the execution of this rotation. Ensure you have enough food supergrest blueblubber as you will take notable damage even if soulsplit flicking properly and using divert on pillars

Black Stone Dragon

The final boss of the Dragonkin Laboratory. She is the main source of the dungeon's primary unique: Draconic Energies draconicenergy, which are used to make the Mage T92 Elite Tectonic set elitetectbody and also drops the gbarge greatercodex

This fight consists of simple mechanics but can be very punishing if mistakes are made. It is also one of the few bosses to auto attack in all three combat styles, with melee hitting especially hard, so it is possible to die just from auto attacks if the player can't out heal with soulsplit, is low on food, and/or can't prayer flick the fight.

Example Rotation:

Phase 1

surge + dive + gdeathsswift + adrenrenewalecb eofspec + pre-place dommine at South Black Hands → ingen + smokecloud + dragonslayer + gricolimitless + rapidsgb eofspec → build with basics until hands spawn

Note: Make sure sgb eofspec is cast before BSD reaches 520k to pre-phase.

Phase 2: Black Hands

⬥ Hand 1:

Equip fularrow + bolg specgricosnipe → finish off 1st hands with basics

Note: This hand should be damaged by pre-placed dommine

⬥ Hand 2:

rapidsnap → finish off with basics

⬥ Hand 3:

ecb eofspec → equip deathsporearrows → build to 100% and 5 deathsporearrows stacks with basics and rapidincendgdeathsswift → finish off 3rd hands

⬥ Hand 4:

Place domminebolg specsnap → basics to finish off

Post-hands BSD

ecb eofspecgricodragonslayer + rapidsgb eofspeccorruptshotgricoshadowtendecb eofspecsnap → finish off with basics/bolg spec and limitless + rapid

Phase 3: Flight

Build to 100% with basics → ingen + smokecloud during flight → build to 4 deathsporearrows stacks → grico to proc deathsporearrows during 5th flight → incendnat → build to 100% → ecb eofspec + adrenrenewal after 6th flight and vulnbomb + dive / surge next to BSD

Post-Flight BSD

dragonslayer + bolg specsgb eofspec → finish off with dbow eofspec / snap / rapid depending on adren and BSD hp.

Mobs

The AoE centre of large mobs such as the dragons and lava strykewyrms is the south-west tile. This is important when choosing which mob to mechchin. Use stickybomb on Celestial dragons when their HP falls below ~28k immediately to prevent healing. Otherwise, use mechchin bindingshot or rapid as they begin to heal. Note that mechchin rapid only prevents on the healing on the main target Celestial, other hit Celestials that are not the main target will still heal. You can also use incend opportunistically for critbuff
