Library Copies an Enchantment Your Troop Already Has
Library has a 50% chance each year to duplicate an enchantment already on an adjacent troop. Place it directly beside your intended carry and give that troop a useful enchantment first; Library does not automatically duplicate every tome you play.
Choose Cards for the Effect You Want Repeated
Library needs an enchanted troop beside it before its copying effect can help. It copies an enchantment belonging to an adjacent troop, rather than copying neighboring buildings or creating a fresh enchantment from nothing. Your first enchantment therefore matters: it supplies the effect you are asking Library to grow.
Choose the enchantment pool to fit the carry. Wizard benefits from the enchantments it carries, while a Warlock using Library for protection benefits from keeping its enchantment selection focused on Steel Coat. Adding an unwanted enchantment gives Library another possible effect to copy instead of the protection you were building toward.
For tome interactions, distinguish Library from Golem and Codex. A tome used on Golem has double effect, while Codex returns copies of a Tome used on it and then self-destructs. Those cards serve different purposes from Library's ongoing duplication of an enchantment already carried by a neighboring troop.
Set Up Library around Your Carry
- Apply your preferred enchantment to the carry. Steel Coat is a concrete choice for a defensive copying plan; putting it on the troop gives Library an existing effect to duplicate.
- Place Library directly beside that enchanted troop. Its effect depends on adjacency, so the Library must touch the carry's plot to contribute to the enchantment plan.
- Keep competing troop plots off Library's remaining sides. When your carry is the only troop touching that Library, its troop selection stays focused on the plot you intended to strengthen.
- Add further Libraries beside the same carry when enchantment copying is your priority. The dedicated multiplayer Wizard layout surrounds the central Wizard plot with Libraries, concentrating successful copies on that troop.
- Inspect the carry's enchantment icons as its stack develops. Hovering over an enchantment icon shows its effect, helping you judge which enchantments you want to keep feeding into the build.
Match Library to Your Carry
| Carry | Enchantment Plan |
|---|---|
| Wizard with enchantment scaling | Give Wizard a useful enchantment such as Combustion, then place Library beside it. Wizard gains damage for each enchantment it carries, so successful copies contribute both the enchantment's effect and its enchantment-based damage growth. Arcane strengthens that damage interaction when equipped. |
| Warlock with Steel Coat | Seed Warlock with Steel Coat and put Libraries alongside its plot. Tome use supplies Warlock's HP growth, while Library supplies enchantment copies. Keep the enchantment selection focused if you want its copying opportunities going toward Steel Coat instead of a wider assortment of effects. |
| Paladin with mixed support | Apply Steel Coat to Paladin and place Library beside it. Put a Blacksmith and Farm on other sides of the Paladin plot: Library grows the protection stack, Blacksmith supports damage and HP growth, and Farm adds units. Keep those supports centered on the same carry. |
| Orbiter beside an enchantment recipient | Place Orbiter beside the troop receiving enchantments so its passive can inherit enchantments applied to that adjacent plot. Check Library's neighbors separately: letting Orbiter also touch the Library introduces another troop target when you may want copies concentrated on your original carry. |
Balance Library Space with Other Support
Decide whether the carry needs concentrated copying or a mixture of support before filling its neighboring plots. The dedicated multiplayer Wizard setup gives those positions to Libraries, while the Paladin setup combines Library with Blacksmith and Farm. Choose the arrangement that supports your carry's actual job rather than surrounding every troop the same way.
For another concrete mixed-support goal, Full-service requires a Blacksmith, Library, Beacon, and Forest buffing the same troop plot. Plan their positions around that shared recipient. Support buildings show visual effects on affected plots, which helps you check where their effects are landing.
Surge offers a separate way to activate a support building: it triggers the targeted building's effect 9 times. Prepare Library's adjacent troop and enchantment pool before spending Surge on it. Treat the extra activations as opportunities for the copying effect, and keep protection in place while relying on chance-based results.
Fix the Mistakes That Waste Library
- An empty enchantment stack gives Library nothing to copy. Apply the useful enchantment to your intended recipient before relying on the building to grow that stack.
- A crowded Library can spread copies away from your carry. Check every troop touching it, including troops on its outer sides, and keep its available targets aligned with your plan.
- Too many enchantment types can work against a focused Steel Coat plan. Each additional type gives Library something else to copy, so choose new enchantments for their value to that specific carry.
- A failed yearly copy does not by itself mean your placement is broken. Library's effect can fail, so judge adjacency and the existing enchantment pool before spending more resources to solve a targeting problem.
- Steel Coat copies still need a suitable matchup. Fast attackers landing many small hits can burn through the protection early, so assess how the carry survives the whole fight rather than judging the build only by its enchantment stack.
