Lifesteal is a workshop upgrade that lets your tower recover health based on the damage it deals. It is a straightforward sustain tool that becomes more valuable as your damage output grows.
Description
Lifesteal heals your tower by a percentage of the damage you deal to enemies on hit. The healing amount is calculated by multiplying your lifesteal percentage by the damage dealt.
This effect applies to any tower projectiles, including those from bounce or multishot. If your build uses multiple projectiles or ricocheting shots, each hit contributes to your healing.
Workshop
Lifesteal is unlocked in the workshop for 2000 coins after you have purchased Thorn Damage. It has 80 levels, starting at a base value of 0 and reaching a maximum of 4.46%.
You can adjust the maximum lifesteal value through trade-off perks, which may raise or lower the cap depending on your choices.
