Description

The Slow Boss, previously known as Boss2, is a slow and tough boss that appears in the Easy, Casual, Legacy Molten and Basic Arena PVP modes. It also appeared in the SFOTH Event, The Classic Event and The Takeover Event. Though the Slow Boss is slower than the Normal Boss and Necromancer, its high health makes it a considerable threat. Later on in the game, it will appear in large, mostly packed, hordes, causing many problems if you lack high DPS towers.

The Slow Boss can be spawned by the Mystery Boss upon its death in the Legacy Molten and Easy modes. In Easy mode, the Grave Digger used to rarely spawn the Slow Boss. The Slow Boss could also have been spawned by the Swordmaster.

Strategy

• Many towers can be used to deal with the Slow Boss on its debut.
  • High-DPS towers like the Minigunner and Turret are able to defeat the Slow Boss rather quickly.
  • Stronger early game towers like the Golden Scout, Militant, Soldier, Brawler, Ace Pilot and Cowboy, when upgraded to higher levels are strong options against the Slow Boss.
• Multiple towers can take advantage of the Slow Boss' slow speed.
  • Short-ranged towers like the Assassin are able to get many more hits in, making them more effective.
  • The Military Base and Crook Boss' units will have more time to shoot at the Slow Boss before colliding into it.
  • The Brawler on Levels 2 and above is able to stunlock multiple Slow Bosses.
• Though not necessary, all stalling towers will work against the Slow Boss, and can slow it down significantly.
  • However, the first Slow Boss in Easy mode is a Boss enemy. This means it is either fully or partially unaffected by all forms of stalling.
  • Do note that the Slow Boss large size makes the freezing, knockback and stunning towers like Freezer, Brawler and Warden less effective than usual.

Trivia

• The original name and appearance were based on the Boss2 from Tower Battles.
• When the Uber Mystery was in the game, it had a chance of spawning the Slow Boss upon its death in Golden and Fallen modes.
• In Hardcore Testing BETA, the Slow Boss had 10 defense.
  • This would be later re-added for the modern version with 25% defense. Although the legacy version has none.
• The death sound Slow Boss makes is a deeper sound than Boss2's from Tower Battles.
• The Slow King and the Mega Slow can be considered 2 Hardcore variants of the Slow Boss.
• Due to a bug, the Slow Bosses spawning on wave 29 of Easy mode were separated by an extremely long amount of time. Because of this, even without skipping the wave, the enemies would not have enough time to spawn, causing them to spawn on Wave 30 instead.
  • Since these enemies would not count as enemies that spawned on Wave 30, you could have them spawn after triumphing by killing just the enemies that spawned on wave 30. You could reach zero base health after triumphing this way, but this would not make you lose.
  • This was later fixed on 12th of March 2022, where the time between each spawn is now quicker, with each spawn being 2 seconds instead of 8 seconds.
