Booster Pack Heroes Shop & Mastery Guide
Learn what coins, Mastery and the purple shop resource buy, with early-demo prices and unlocks.
On this page＋
Use coins for packs, Mastery for the upgrade tree, and the purple resource for shop upgrades. Keeping these balances separate makes the early game much easier to follow.
What each resource buys
| Resource | Main use | Early browser-demo example |
|---|---|---|
| Coins | Packs, boxes and shop purchases | Basic Pack: 2 coins |
| Mastery | Hero, spell and other tree upgrades | First Squire attack node: 10 Mastery |
| Purple shop resource | Shop improvements | Unlock shop refresh: 1 purple resource |
Buying your first pack
The opening shop gives you 3 coins to spend. Buying a Basic Pack for 2 leaves 1 to spend. The pack opens during the following battle when you keep the cursor over it.
A later 5-coin box contains 3 Basic Packs and grants 3 Mastery when opened. Prices describe the browser-demo progression shown here; check the current shop before purchasing.
Raise your income through tasks
Early tasks increase the coins available for shopping. Opening packs and reaching kill milestones can move income from 3 to 4, 5, 6 and beyond. Follow the task currently displayed rather than assuming every run has the same objective.
Refreshing the shop
Unlocking refresh costs 1 purple resource. The first refresh then costs 1 coin, with the next refresh shown at 2 coins. The unlock and the individual rerolls use different resources.
The October update also changed shop rolls to take income into account. Old advice built around a completely predictable shop may no longer fit.
Claim discoveries before buying upgrades
Collection rewards can add Mastery outside the usual battle payout. Claiming the reward for your first Squire discovery awards 10 Mastery. A colorful Squire discovery also awarded 1 purple resource; do not confuse that reward with the card’s combat stats.
