concentration, 1 minute/mana

As two actions, you impart latent luck upon up to two creatures you can see within 5 meters. Whenever a target makes a skill check or a saving throw before the spell ends, it rolls with advantage.

Additionally if you are one of the targets, whenever you are attacked before the spell ends, the attacker rolls with disadvantage.

Augment

You can target two additional creatures for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
