What the fair is
Champagne Fair is a two-day market at the start of each cycle (it first unlocks after your kingdom's third Hall of Governors). You trade spare hero materials for Fair Vouchers, then spend the vouchers in a shop whose top shelf holds Mithril, Forgehammers, pet advancement materials, and widgets. Nothing about it requires fighting or spending money; it's an arbitrage window for things already sitting in your bag.
What converts, and for how much
| Material | Vouchers each | Exchange limit |
|---|---|---|
| Widgets | 200–500 (by generation) | 100 |
| Mythic hero shards | 100–300 (by generation) | 500 |
| Epic universal shards | 10 | 500 |
| Rare universal shards | 6 | 500 |
| Epic skill books | 4 | 500 |
| Rare skill books | 2 | 500 |
The table has one loud message: generation-scaled items carry the value. A single widget pays as much as dozens of rare shards, and mythic shards of your newest generation outconvert everything below them. The materials worth feeding in are the ones with no better home: duplicate shards for heroes you'll never ascend further and skill books your roster has outgrown. Shards your roster still needs are worth more as heroes than as vouchers.
The shop order
- Mithril. Nothing else in the game hands it out this cheaply, and it's the scarcest input for endgame hero gear (it also scores 40,000 a piece in KvK prep, so fair Mithril is event points on layaway).
- Gen-current hero gear chests and hero gear XP.
- Universal mythic shards, which turn into whichever hero your roster actually needs.
- Advanced training marks and pet advancement materials.
- Everything else, in whatever order your bottleneck dictates.
Never spend vouchers on raw resources (bread, wood, stone, gold). Gathering and events supply those for free, and every voucher spent there is Mithril you didn't buy.
The hoarding rule
Fair Vouchers never expire and carry over between fairs, which changes how to play a thin month. If you can't afford the shop's top shelf this fair, convert your materials anyway and sit on the vouchers; next month's fair sells to a richer you. The same logic runs in reverse for materials: shards and widgets have no fair value between events, so bank them through the month and convert during the two-day window rather than dribbling them into lesser sinks.
FAQ
Should F2P players buy resources here?
Only in a genuine emergency, like a building upgrade blocked mid-event. The voucher-to-resource rate is poor, and the Mithril you skip doesn't come back.
Which shards should I keep out of the exchange?
Anything your active roster still ascends with, and any generation you're still recruiting from. The Gen 8 guide covers why holding universal shards ahead of a generation launch usually beats converting them.
When does it run?
Monday and Tuesday of week 1 in each cycle, alongside the start of Alliance Brawl; the Event Calendar has your next window.
