River Vials

River vials are cosmetic items that alter the appearance of the in-game river. Having a river vial tool in the armory allows players to purchase an in-game vial from the fountain shop, which can then be used by the hero.

Information

 * The altered river appearance lasts 15 minutes.
 * Vial tools come with a limited number of charges.
 * Using a vial will consume one charge from the tool in the armory.
 * Once all charges are spent, the tool disappears.
 * Charges are only consumed if the river effect lasted its full 15-minute duration.
 * Charges are not consumed if they are overridden by a stronger vial, or if the game ends before their full duration.

Priority

 * Rarer vials are considered "stronger" than more common ones.
 * Using a stronger vial will override an existing effect from a weaker vial.
 * A weaker vial cannot be used if a stronger vial is already in effect.
 * The following is a list of vial priorities, from strongest to weakest:
