Amplify Bot is one of the bots you can deploy alongside your tower. While active, it amplifies the damage dealt to enemies inside its range, making it a strong tool for pushing through tougher waves.
Description
Amplify Bot increases the damage dealt to enemies caught within its area of effect while it is active. Anything inside the bot's range takes amplified damage for as long as the activation lasts.
Unlocking/Upgrading
Amplify Bot is bought and upgraded through the Event Shop menu, the same as every other bot. The medals needed to unlock it scale with how many other bots you already own. Each of its four upgrades begins at a base cost of 100 medals, with the price rising by 40 medals per level.
Duration
The Duration upgrade extends how long the bot stays active once triggered. It begins at 20 seconds and can be raised through 30 levels, with each level adding 0.5 seconds.
Cooldown
Cooldown sets the gap between the bot's activations. It starts at 120 seconds and has 15 levels, each one shaving 3 seconds off the wait.
Bonus
The Bonus upgrade raises the damage multiplier applied to enemies in range. It starts at x3.50 and runs for 30 levels, gaining 0.4 per level.
Range
Range determines how large an area the bot covers while active, and it scales with your tower's range. The upgrade starts at 25m and has 18 levels, each adding 2m.
