Beginner 3v3 Depths Holy Healer

Weapon: Your E, when used, places a buff on you that increases your healing by 5%, stacking up to 3 times for a total of 15% increased healing. You should spam this ability just before that buff runs out to maintain this healing buff in case you unexpectedly enter into combat. Your 4th passive is crucial if opponents have a way to interrupt your W. You can change it to 1st passive if you are fighting a team without a way to interrupt your W. Hallowfall is an okay weapon to use instead, but you will miss out on healing in favor of a skill that can keep you alive (Hallowfall E dash).

Off-Hand: Whether you use Sarcophagus or Mistcaller is up to your personal preference. I would recommend that you use Sarcophegus to start and then branch out until you become more comfortable with Depths fights.

Head: This ability makes your mana costs 0 for the duration. If you use it as soon as it comes off cooldown, it will be active 50% of the time. This ability ensures that you don't immediately run out of mana.

Chest: Everlasting Spirit on your Cleric Robe works well against most comps (Claymore, Bow of Badon) in the Depths, especially one-shot comps. Frost Shield is ideal against damage over time comps (Rotcaller, Regular Bow). Mistwalker jacket is an excellent, though expensive, option. It makes you immune for a long period of time, and when you aren't being targeted, you can cast a few spells to keep your team up during the duration and the immunity will almost immediately come back online.

Shoes: Use Refreshing Sprint to move away from the enemy DPS. Usually, you can run through them and past the enemy healer, making it so that the enemy DPS have to run through your DPS to get to you. The same can be done with Dodge roll, which you can also save to dodge crucial abilities (Carving E, Bear Paws E). Use Mercenary shoes to break out of crowd-control effects or leap to safety when there are no crowd-control threats. Use Mistwalker Shoes to dash away from your team early in a fight to keep yourself safe. Reactivate the dash to return and heal your teammates. Use your dash to lead opponents away from your marked location to create time for your DPS to win the fight.

Cape: Martlock cape is the best cape.

Potion: Resistance potion is your longest defensive cooldown aside from Martlock cape. You will usually use Resistance potion after your armor ability is purged or runs out.

Food: Avalonian Omelets are the best food. Regular omelets are fine on a budget.
