The Workshop is where you spend coins on permanent upgrades for your tower, separate from the cash upgrades you buy mid-run. Once you progress far enough, it also houses Workshop Enhancements, a second layer of multipliers that sit on top of your existing stats.
This page covers how the Workshop and its Enhancements are structured, when they unlock, and what each individual enhancement does.
Workshop
The Workshop offers three categories of upgrade: Attack, Defense and Utility. You buy them with coins between rounds, and anything purchased this way is permanent, unlike the cash upgrades bought during a round, which reset when the battle ends. If you want to redo your coin spending, a Workshop Respec will refund it.
The Workshop menu is also where you unlock and upgrade Ultimate Weapons.
Workshop Enhancement
Workshop Enhancements mirror the same Attack, Defense and Utility split as the base Workshop. Each enhancement is a multiplier you level up with coins, and new ones within a category become available by sinking coins into the other enhancements of that same category.
Unlock
Workshop Enhancements become available once you reach tier 12 wave 60, and you also need to have finished the Workshop Enhancement lab research. The cost table below lists what each level costs once the feature is open.
| Level | Time | Cost | Value |
