Hello guys,

The Boss Destroyer achievement is one of the most time-consuming achievement in the game.

The hardest boss is usually confused with other bosses or the player doesn't know how to exactly get it to spawn.

Here is some info on how to get it to spawn him the most efficient way.

I unlocked the achievement after I built the 3rd castle. He spawns in the Survival and Endless modes too.

What I simply did was to survive around 7-8 waves in a row without my troll and castle dying and he spawned. You might need to survive way more waves in Survival and Endless modes though.

You could easily confuse the hardest boss since it looks similar to another boss but you will find the screenshot of how he actually looks like down below.

Note that the wave counter does not matter. I killed him while around the 60th wave. That is because I was farming the other achievements (tower upgrades, fully upgraded troll, etc...)

One more thing, you MUST give him the last hit, or it will not count. I wouldn't worry because there are several ones in a single wave after some time.

If the towers steal your kills, just deconstruct them by changing the tower type and do not assign builders until the end of the next wave.

The hardest boss is the one on the top right, with the horns.
