Blaze

Strong area-of-denial abilities and access to debuffing talents, Blaze is one of the frontlines in the game, providing the proper tools to defend his team. Given that Auriel has very poor mobility, his peeling capabilities are extremely valuable.

Yrel

Yrel can effectively stick to her target with her dive abilities and displacement tools. In addition, she can act as an emergency off-healer thanks to Gift of the Naaru, which can be useful when Auriel has no Hope or means to generate any.

Diablo

Diablo's kit is all about displacement through an aggresive playstyle. His Shadow Charge directly synergizes with Auriel's Detainment Strike, since both stun enemy Heroes when they collide against obstacles. In addition, Lightning Breath can provide massive Hope to Auriel, being a good option to Bestow Hope on Diablo when he uses it.

Leoric

His Entomb serves as an obstacle that Auriel can stun her opponents against with Detainment Strike. In addition, his strong self-healing capabilities means Auriel doesn't have to heal him as much and can instead focus on her other allies.

Always keep up with the strong ones

Bestow Hope should always be on someone, preferably on a damage dealer Hero. Avoid having it on tanks, but if there is no other option, have it on them. Learning what other Heroes can do is key, and encourages the player to swich Bestow Hope between characters to get the max of the abilities translated into Hope (i.e. switching to Azmodan when he is about to use Globe of Annihilation, etc.).

Always start team battles with enough Hope

Ideally, Auriel should always be ready for an engage against the enemy team with her Hope full. This is not always possible, however, since she can only generate Hope when actually hitting anything. Because of this, it is very important to always be a contribution for the team, since she has a strong waveclear through Sacred Sweep, which when hitting an entire group of minions provides a lot of Hope.

Maximize your reservoir

The core of this build is to provide Auriel with a powerful endgame healing through the interactions of Glimmer of Hope and Reservoir of Hope to increase Auriel's maximum Hope energy, which will translate in more healing. The payoff is huge, as if built enough, it can outheal the likes of Rehgar's Ancestral Healing.

The idea is to always have the effect provided by Glimmer of Hope active before casting a fully powered Ray of Heaven, increasing the max energy while retaining 75% of energy, and then picking up another globe before casting again, repeating the process. While it can be hard doing that during actual teamfights, this strategy is great when waveclearing and doing Mercenary Camps; and in this case it is encouraged to cast Ray of Heaven whenever it is full to increase Auriel's max energy.

Master your stuns

Detainment Strike has a very small hitbox and it can be difficult to land properly, specially when you sometimes can end up actually saving the opponent by knocking him away when your team is about to kill them.

Once mastered, however, it becomes a powerful kill setups when actually stunning the opponent. Playing around with your opponent so they have their backs to a wall is a risky, yet effective maneuver if done correctly. Repeated Offense greatly aids in this matter since the extra knockback is often enough to surprise opponents and stun them against obstacles.

One of the things that makes this ability so great is that the stun applies when hitting virtually any kind of obstacle, not only walls and structures. These are:

• Leoric's Entomb;
• Sonya's Arreat Crater, the level 20 upgrade to Leap;
• Thrall's Worldbreaker, the level 20 upgrade to Sundering;
• Tassadar's Force Wall;
• Nazeebo's Zombie Wall;
• Sgt. Hammer's Barricade, the level 4 upgrade to Concussive Blast;
• The vase spawned by the Garden Terror in Garden of Terror;
• The doubloon chests that spawn in Blackheart's Bay.
