Puzzles & Chaos: Frozen Castle War Hall Scrolls Guide (The Castle 22 Spending Gate)

Castle 22 is the first real spending gate in Puzzles & Chaos: Frozen Castle. Most players hit it without warning. This is what you need to know before you get there.

What is the War Hall in Puzzles & Chaos: Frozen Castle?

The War Hall is a required building on the path to Castle 22. It is not optional and it cannot be upgraded through standard construction materials. The War Hall requires War Hall Scrolls to level up, and War Hall Scrolls are purchased exclusively with Diamonds. There is no farming path, no event reward route, and no alternative acquisition method.

For players who top up a lot, this is the first moment where Diamond budget planning intersects directly with a hard Castle progression gate. Accounts that reach Castle 22 prep with insufficient Diamond balance stall. The upgrade does not start until the Scrolls are purchased.

How many War Hall Scrolls does Castle 22 require?

War Hall level 21 requires multiple Scrolls before the upgrade can begin. The requirement gates the path to Castle 22. The exact Scroll count per War Hall level scales with the upgrade tier, so the cost to reach War Hall 21 from lower levels accumulates across multiple upgrades, not just the final one.

For accounts approaching Castle 22 for the first time, the practical planning rule is: do not assume your current Diamond balance will cover it. Check the War Hall upgrade requirement before spending Diamonds on anything else in the pre-Castle 22 phase.

How much do War Hall Scrolls cost in Diamonds?

War Hall Scrolls are purchased through the in-game Diamond shop. The Diamond cost per Scroll is fixed. The total Diamond outlay for reaching War Hall 21 depends on your current War Hall level and how many Scroll-gated upgrades remain between your current level and level 21.

For accounts tracking toward Castle 22 on a timeline, the correct approach is to calculate the remaining Scroll requirement as early as Castle 18 or 19 and reserve Diamond balance for it. Spending Diamonds on speedups or hero banner pulls in the Castle 18 to 21 range without accounting for the War Hall Scroll requirement is the most common reason high-spending accounts stall at the Castle 22 gate.

War Hall Scrolls and the Castle 25 gate

The War Hall Scroll requirement does not end at Castle 22. The Scroll-based gating continues through higher War Hall levels that gate Castle 25 and above. The pattern: each major Castle milestone has a corresponding War Hall level that requires Scrolls, and the Scroll cost per upgrade increases with the War Hall level.

For accounts planning their spending timeline across Castle 22, 25, and 30, the War Hall Scroll budget is a recurring Diamond allocation, not a one-time cost. Accounts that treat Scroll purchases as planned Diamond allocations rather than reactive emergency buys keep Castle progression on schedule without the stalls that reactive spending creates.

How to plan your Diamond budget around War Hall Scrolls

Check the War Hall requirement before any major Diamond spend. If you are between Castle 18 and Castle 25, open the War Hall upgrade screen and note the Scroll count required for the next level before spending Diamonds on speedups, hero pulls, or event entries.

Hold Diamond balance specifically for Scroll purchases. The War Hall gate does not offer a workaround. If you spend the Diamond balance needed for War Hall Scrolls on other purchases and cannot afford the Scroll gate, Castle progression stops until the balance is rebuilt.

Build the War Hall in parallel with Castle upgrades. The War Hall level required for each Castle tier needs to be reached before the Castle upgrade itself can complete. Accounts that neglect War Hall upgrades until the Castle gate forces them find themselves double-purchasing: Scrolls for the War Hall and then speedups for the Castle timer, both at the same time.

Prioritize War Hall Scrolls over event pack spending in the Castle 20 to 25 range. Event packs during this phase can always wait for the next event cycle. The War Hall gate cannot. Missing an event cycle costs one cycle of hero shards. Missing the War Hall Scroll purchase costs Castle progression days or weeks.
