Land Mine

From The Tower - Idle Tower Defense Wiki and Guides

Land Mines have chance to spawn on an enemy kill. Once set they will trigger once enemy will come into explosion radius.

Damage Calculation[edit | edit source]

Land mine damage is using an average crit factor and average super crit factor based on the activation chances. The damage can be calculated with the following formula:

Land Mine Damage = Land Mine Damage % * Damage * (1 + Critical Factor * Critical Chance) * (1 + Super Crit Mult * Super Crit Chance * Crit Chance)

Workshop[edit | edit source]

A defense workshop that has a chance to spawn a mine, dealing damage to all enemies in range when triggered.

Land Mine Chance[edit | edit source]

Chance of enemies dropping a land mine.
Unlocked in Workshop.pngWorkshop for 400,000 coins with Land Mine Damage and Land Mine Radius after Shockwave Size and Shockwave Frequency. There are 50 upgrades that increase the chance by 0.60% for each upgrade for a maximum of 30.00% chance to spawn. Once spawned, the land mine will explode after a set time that can be increased with the Land Mine Decay lab.
