Spinel Tonic

Spinel Tonic is a Lunar Equipment in Risk of Rain 2.

Like all Lunar items, the Spinel Tonic has a powerful effect and drawback.

Activating this item gives the player +100% damage, +70% attack speed, +20 armor, +50% maximum health, increases movement speed by +30%, and increases their passive health regeneration by +300%. This effect lasts for 15 seconds. This effect also adds a visual filter to the screen, displacing the outlines of items and other HUD effects, such as the Huntress' target reticle and the similar reticle of the Royal Capacitor. It also turns the screen very slightly fish-eyed, blue, and grainy, though these effects are fairly minor.

Upon the effect ending, however, there is a 20% chance to gain a stack of Tonic Affliction, which reduces all stats by -5% while the player is not under the effects of the Tonic. The debuff comes in the form of a greyed out, special type of item, similar to a consumed Dio's Best Friend. Tonic Affliction stacks, giving an additional -5% to every stat each stack.

Spinel Tonic is unlocked through the "Cosmic Explorer" challenge (Discover and enter three unique portals).

If under constant effect of this item, through Gestures of the Drowned, or many Fuel Cells, the negative effects of the Tonic will be bypassed, as long as the Tonic is always equipped.
