Use these supers wisely and form an effective team composition before heading into the raid. The new Well of Radiance provides healing and a DPS buff for anyone who stands in the Well. Dawnblade lets you roam around and kill a ton of enemies. For Warlocks, Dawnblade and the new Solar Super will be your best bet.
Combine the tether with the Exotic Boots 'Orpheus Rig' in order to get your Super ability back almost instantly. The Nightstalker's tether allows you to stun and weaken a ton of enemies at once. For Hunters, the Void subclass is by far the best choice. Solar Hammers are super effective at clearing enemies and the new Sentinel Titan can put up a massive shield to protect you and your allies. For Titan players, the Solar and Void subclasses will be the most effective.
Spoiler alert: There are 6 main encounters in the raid and each encounter has a ton of enemies.
