Frequently asked

Quick answers about the current Collector event.

How the math works

Transparency on the numbers behind every calculation.

Crest average

Community-reported average is ~100 crests per 10 draws. Not official — actual drops vary. Unlucky runs may need a few extra draws; lucky ones finish early.

Duplicate conversion

Duplicate skins convert to crests: Collector · 240, Special · 45, Elite · 36, Basic · 16. The ~100/10 average already factors these in.

Why the 10× is always used

The one-time 10× draw costs 350 💎 (30% off). Buying 10 singles would be 500 💎. Net savings: 150 💎. Always optimal, even if you skip spend tasks.

Spend-task mechanics

Spend thresholds (100 / 250 / 500 💎) count draw purchases only within the first 7 days. Starlight purchase does not count. The 10× draw (350 💎) plus ~6 daily draws hits 500 💎 exactly.

Milestone rewards

At cumulative draw counts: 20 · +1 token, 40 · +1 token, 90 · +5 tokens, 110 · +50 crests. Single-skin targets rarely reach 90+.

Starlight net cost

300 💎 cost − 300 COA refund = 0 💎 net. The COA refund is spendable 1:1 inside the event and offsets draw costs. Starlight also unlocks +2 free tokens via the event task.
