Weapon Oils and Vials

Weapon oils and vials are an alchemy output in Fatekeeper. They coat a weapon for a number of swings, adding an elemental damage type, a status effect, or another modifier on hit. Vials let melee builds mimic some of the elemental flexibility of casters, and they let casters extend their elemental theme into close range without committing more skill points.

What Vials Do

• Add elemental damage. Fire, ice, or wind-themed coatings add elemental damage on top of the weapon's base damage.

• Apply status. An ice vial freezes; a fire vial burns; specific named vials may add unique effects.

• Set up combos. Ice vials are the easiest non-magic path to Shatter.

How To Get Them

Vials are produced through the alchemy system, by combining three ingredients and choosing the weapon-vial output. Discovered recipes can yield vials with unique properties beyond raw ingredient sums.

Specific named vials, swing counts per coating, and stacking rules between vials and ingredient effects are unconfirmed. The system has been described in dev material with the understanding that more details are coming in a future alchemy-focused dev post.
