The Vault

How the Vault is organized

Every tree is split into groups. A group has to be unlocked with Keys first (the price is in each table caption); after that each node inside it is levelled one Key purchase at a time. The "per level" column is what one level adds; "keys / level" lists the price of each level in order, because most nodes get more expensive with every level, and "max levels" is how far a node goes — all three read out of the 29.0.1 build itself. Power nodes are mostly 5 levels deep, Harmony nodes are single toggles or short ladders, and every Enemy node runs 30 levels, from 25 Keys for the first to 103 for the last (1,662 per node) — which is why the Enemy tree alone accounts for the bulk of the 73,022-Key total.

Power tree

Power is the tower-stat tree: attack, defense, economy (utility) and Ultimate Weapon boosts. Nearly every node gives +5% per level over 5 levels for 10, 20, 40, 70 and 110 Keys (250 per node); the exceptions — Defense %, Orbs, Shockwave Frequency, Death Defy, Wall Rebuild and the two enemy-skip nodes — are the ones worth planning around because they are either rarer stats or start at 20 Keys a level and climb from there.

Harmony tree

Harmony is the non-tower side: automation for cards and Ultimate Weapons, extra presets, respec discounts and sliders. Most nodes are single-purchase toggles. The two Bastion descriptions are the game's own English strings, read out of the 29.0.1 build; the rest are carried over from our earlier Vault write-up. Nodes marked — have no verified description yet.

Enemy tree (new)

The Enemy tree is the expansion's big addition: 36 nodes that shave 1% per level off a specific enemy type's attack, health, speed, range or radius (plus a few positive ones — Basic Coin Bonus, Boss Common Drop Chance, Saboteur Miss Chance). Every node has 30 levels whose price climbs from 25 to 103 Keys, so a single maxed node is 1,662 Keys and a full group of nine is 14,958 before the group unlock. Groups follow the enemy roster: Simple, Advanced, Elites and Fleets.

Where the Keys come from

Keys are awarded for placements in the two top tournament leagues: Legends pays from 25 Keys for 1st down to 1 Key (ranks 16–24 get 1 Key since v29), Mythic pays between 8 and 50 Keys. The other leagues pay none, which is why the Vault is paced by how often you place and how high. See the Keys page for the placement table, and the Legend battle conditions guide for what those tournaments look like.

FAQ

**How many Keys does it take to max the Vault?** 73,022 Keys across all three trees — 72,577 for the node levels and 445 for the group unlocks. The Enemy tree is 59,832 of that, by far the largest share.

**What is new in the Vault?** The Enemy tree (36 nodes, 1,080 levels) and a group structure with unlock costs; Harmony also gained new automation and slider nodes such as the Damage Cap Slider, Black Hole Size Slider and Life Saving Ordering. Version 29 added two more Harmony nodes — Bastion Automation and Smart Bastion Automation — for the new Bastion card.

**Which Vault upgrades should I buy first?** The automation toggles in Harmony are cheap (5–25 Keys) and change how you play immediately; in Power the 10-Key +5% nodes are the efficient bulk, and the Enemy tree is the long-term sink.
