Frost Treasure

Three reward tiers

Every draw pays out exactly one reward. The tier sets the odds, the guarantee and how many Treasure Points it banks.

Pity carries over between events

How the chance ramps

The chance climbs with every miss and hits 100% on the last draw. The counter resets once the tier drops.

Free voucher income —S1 Season Supply Voucher

Everything obtainable without paying. Vouchers survive the event and carry into the next run, just like pity progress.

One run free-to-play is not enough: 68 draws are only a 15.1% shot at the gun, while the hard guarantee sits at draw 100.

Gold, diamonds and ads cannot buy the voucher: it is on no shelf in the shop or the exchange, and the ad pack pays diamonds and gold only. The other token, the Fortune Key, comes from the game's general economy. The remaining event tasks pay 200 Treasure Points.

What a guaranteed weapon takes

1. Free vouchers: 60 up front + 8 landing on the way (milestones at draw 10 and 40, the pass's start node) → 68 drawsno money
2. Buy the pass — its paid lane hands out vouchers as you go: 75 draws$9.99
3. Buy 25 more vouchers — that reaches draw 100, the hard guarantee(cheapest: 1×$0.99 + 2×$2.99 + 1×$4.99)$11.96
4. Total for a guaranteed gun on draw 100$21.95

The best value voucher is the $0.99 pack (3 of them, $0.33 each); it resets daily, so spreading purchases across the run comes out cheaper. Or buy the weapon outright in its own pack for $99.99.
