Reveler's Tonic

The Reveler's Tonic was an item in the Revelry spring event, given by Eva Levante on your first visit to the Tower. You fill it with Reveler's Essence by defeating bosses in the Verdant Forest and completing other activities. Spending 50 Reveler's Essence on one of its three options lasts one hour and speeds the recharge of a chosen ability: Proud (class ability), Energetic (grenade) or Friendly (melee).

Essence can also be exchanged with Eva for rewards. The event's headline reward was the Arbalest Exotic, which cost 300 Reveler's Essence.
