vKits are evolving kits on Skyblock Retro. Claim them with /vkit every 4 days. Every claim has a chance to evolve the kit, up to Level 5 (Armor goes up to Level 6), and each level makes the rewards better.
vKit Gem - redeem it for a 25% chance to permanently unlock that vKit (20% for Demigod). Already own it? You get a free evolve roll instead.
Instant Unlock - unlocks that vKit permanently, right away. No rolls.
Evolution Gem - a 50% chance to evolve any vKit you own to the next level.
Ascension Stone - ascends a piece of Demigod gear into God tier.
Gems and stones need you online. Unlocks are applied even if you are offline.
