Preparing for 3-3 DoA teach runs

Join the DoA teaching Discord if you haven't already. You'll need to prepare a mesmer with all the equipment, get checked by a teacher, and then you can start doing some runs!
Make sure to read all the skills on your bar when starting a new role, so you understand how to use them properly.

Empathy

/ Empathy

FC: 12+3, Dom:12+1+3 OQpnAwBhAPEphasG0SwJgpjNoGw0jNJOF

Empathy is the most basic role, so get ready for that one first. No DoA experience is required, but you should understand the concept of getting into cast range of your target before activating your skills.

Armor

Standard armor set	High health armor set
Required This armor set is required, and will be your standard armor in DoA: • 5x Radiant Insignia • +1 Domination Magic headpiece • Rune of Superior Vigor • Rune of Superior Domination Magic • Rune of Superior Fast Casting • 2x Rune of Attunement	Recommended A high health armor set is not required, but is very useful to have, and can save your life in an emergency: • 5x Survivor Insignia • +1 Domination Magic headpiece • Rune of Superior Vigor • 4x Rune of Vitae

Weapons

These weapons are required:

40/40 Domination Magic wand and focus	+30e/-2 Domination Magic high energy set	Any max shield with +10 armor vs demons
Required Can be crafted in Vasburg Armory/Leviathan Pits This will be your standard weapon set.	Required Can be crafted in Maatu Keep Switch to this when you need more energy; switch back to the 40/40 when you're not using skills.	Required You can ask us for a free one - we have plenty Together with a main-hand weapon (can be your standard wand), this will be your defensive set.

Recommended
An energy-hiding weapon is optional, but recommended. It can be any main-hand weapon, but must have -5 energy ("Brawn over Brains" inscription). Combine it with your shield, and use this set to hide energy while spiking the Darknesses.

Pcons

Required
At the start of every run, you need at least 20 each of:

Birthday Cupcakes
Candy Apples
Candy Corn
Scrolls of Resurrection
Personal Death Penalty removal items (Pumpkin Cookies are ideal - do not use items that affect the whole party)
Throwaway summoning stones (you don't need as many as 20, and any type of summon will do)

When you can afford it, buy a full stack of each item.

Recommended
These pcons are not strictly required, but will improve your performance significantly, and the cost is negligible compared to the profit from DoA:

Golden Eggs
Lunar Fortunes
Slices of Pumpkin Pie
War Supplies
Powerstones of Courage or Seals of the Dragon Empire

Titles

Required

Rank 5 Norn (Slayer of Wurms) or higher - for "You Move Like a Dwarf!"
There is no minimum Lightbringer requirement, but make sure you picked up the Lightbringer effect in Chantry of Secrets.

Video

You don't have to watch a tutorial before you start, but you can if you want. This can be particularly useful if you've already learned the basics and want to make sure you're doing everything perfectly. Remember to turn on subtitles for extra instructions.

Backfire

/ Backfire

FC: 12+3, Dom:12+1+3 OQhnAwBhAPEgRYIG0SwJgpzGAHw0jN5NF

Backfire is also a beginner role, but you'll need all the same equipment as Empathy. Required: You also need to be able to quickly and consistently get into the veil glitch spot - practice this in your own time.

TK

/ TK

FC: 12+3, Dom:12+1+3 OQdCAsw0SwJgpTQgc50TMZnD

Once you've got some experience on Empathy and Backfire (at least enough to max your Lightbringer title and get familiar with the 3-3 DoA tactics), it's time to learn TK. The role is a little bit more challenging, but not much extra preparation is needed:
Required

Longbow/flatbow - any one will do; the mods are not important.
Ghastly Summoning Stones - as TK, it's your job to use one in the second room of Foundry.
Rank 5 Asura (Not Too Annoying) or higher - needed to maximise your Pain Inverter.

VoR

/ VoR

FC: 12+3, Dom:12+1+3 OQljAwCs5QuNbAmOCOwlTP2k0l

After learning the other mesmer roles and developing a good understanding of DoA tactics, you can start doing VoR. The build is not difficult to use, but you will be responsible for the highest share of the damage, and it's your job to call spikes, so you should be able to speak clearly on voicechat. The only additional requirements are:
Required

Tengu Support Flares - for the last spawn at Gloom cave
Rank 5 Vanguard (Shadow Agent) or higher - for Ebon Escape

UA

/ UA

DF: 12+3, BM:11, Prot:6+2 OwIT8MIbX6uKHUuE6gukhAg4BEA

You can also start learning as a monk, but it's definitely better to do some runs as mesmer first. As a support player, you have to focus on multiple tasks at once and react appropriately if something goes wrong - this can be tricky if you don't already know the tactics.
