Similar to Push Strategy, aura stacking is simply putting a team together with passive auras that benefit the entire team. These may be offensive auras such as those mentioned above, or defensive auras (Rubik’s Null Field, Wraith Aura).
In this strategy, getting aura items early on such as Ring of Basilius and Headdress synergizes well with the strategy. Aura stacking gives everyone bonus stats when grouped up, making them stronger with less items. However, this strategy is only strong when the team is grouped together.
