"A firework tech who supports the team by giving them detection and grants chance for towers to shoot a firework"

―Inventory Description

Description

The Firework Technician is a support based tower that can only be obtained from completing a specific Mission Quest. Either the 🇺🇸 Rise for the Pledge! or Happy New Years! quests must be completed to get the Firework Technician, either of which costs Coin 650 to start. Currently, the 🇺🇸 Rise for the Pledge! quest can be started.

At the beginning of each wave, Firework Technician grants all 3 detections; hidden, lead and flying, for a few seconds to all towers within its range, with the duration depending on the level. Additionally, all towers in its range at all times will have a chance to fire out a firework. The chance depends on the tower's firerate and the Firework Technician's firework shot percentage cap. At base, it is set to 0.5 which is a maximum chance of 50% and at Level 4 it is set to 1, a maximum chance of 100%. The maximum chances however, are quite unlikely to actually ever be reached outside of Sandbox mode, where the tower's firerate can be set to high numbers. Fireworks are fired out on impact, which is when enemy receives damage from the tower's main attack. If a tower can hit multiple enemies, in most cases this means each enemy damaged will have a chance to make the tower generate a firework. For example, the Rocketeer will generate one for each missile, the Necromancer will generate one for each enemy hit by its projectile or each one of its beams, and the Hallow Punk has a chance to generate an infinite number of fireworks as each enemy damaged by its explosion has a chance to generate one. Not all towers can generate fireworks and units are completely unable to generate them. These fireworks will be fired out at the hit enemy which generated the firework and deal their own firework damage. While stated to be additional damage, the damage from them is not added to the tower's damage, it is instead just its base damage. Fireworks will create explosions which deal damage to enemies hit, bypassing defense, dealing damage to Lead enemies and being boostable by Damage Buffs, these explosions have no damage drop off, and will also set the enemies on fire, dealing additional burn damage. The chance of a firework being fired is calculated as:

$\frac{\text{Firework Shot Chance Cap}}{1+2.718^{(-0.5\times (Firerate-6))}}$

Where Firework Shot Chance Cap is taken from the Firework Technician, and Firerate is taken from the tower that fires out the firework. Firerate in this case is the statistic displayed with the hourglass to the right of the tower. In most cases, this is the firerate statistic (the time between each shot), though in some cases it may be the burst cooldown (time between bursts), like the Elementalist, the spawnrate, like the Military Base or just unrelated to any statistic it has, such as the Trapper. This means towers with a slower firerate have a greater chance to fire a firework. The firerate is not calculated with the Firerate Bug.

The Firework Technician has a placement limit of one per player.

Strategy

• The Firework Technician's range is quite small, so it is recommended to use Range Buffs from the DJ Booth or alternatively, using the Range Flag consumable with it.
  • The DJ Booth can also be useful to boost its damage, as its fireworks are affected by Damage Buffs. Furthermore, DJ Booth may also be used to reduce its upgrade costs as they are quite expensive.
    • Do note that the Firework Technician itself needs to be within the range of the Damage Buff giver, not the tower that the firework is being fired from.
• As the Firework Technician has a placement limit of only one, its placement should be strategized for optimal effect on nearby towers.
  • Multiple Firework Technicians can be brought into a match, though do note that their effects will not stack. For example, a tower with the firerate of 100, which is in range of 100 Firework Technicians, will only fire one firework instead of 100, despite having a guaranteed chance to do so.
  • You can also use the Hacker's Hologram Tower ability to clone more Firework Technicians, but this can be costly.
• It is recommended to pair it with low firerate towers such as the Minigunner or area of effect towers such as the Rocketeer in order to fully optimize and maximize the firework shots.
  • While towers with higher firerate do have better chances than towers with lower firerate, they are still not nearly as optimal. For example, a tower with a firerate of 0.1 in range of a Level 4 Firework Technician will have a chance of around ~4.98% to fire a firework, while a tower with a firerate of 1 will have a chance of around ~7.59%. A tower with a firerate of 0.1 will be more likely to fire out a single firework in the time it takes the tower with firerate of 1 to fire a single shot.
    • It should still be noted that towers with an exceptionally high firerate, such as the Level 4 Ranger, have a significantly higher chance of generating a firework per shot.
    • However, unless a tower's firerate exceeds around 12 with a Level 4 Firework Technician (where there is over a 95% chance of generating a firework), this is not guaranteed.
• Multiple towers which hit many enemies at a time will have a chance to generate a firework for each enemy hit. Because of this, towers like the Hallow Punk, Cryomancer, Electroshocker or Rocketeer can generate multiple fireworks at once, and in general have a higher chance of generating at least one firework. This increases their DPS exponentially, so it is recommended to place a Firework Technician near these towers or vice versa.
  • Do note that not all towers are capable generating it. A full list of towers that can generate fireworks is shown at the end of this section.
• The Firework Technician's ability to provide towers with all detections is very useful. While it is only temporary and its effects only take hold at the start of each wave, it can still prove great for towers like the Swarmer and Ranger, with the provided detections greatly increasing its effectiveness against enemies of specific Attributes.
  • This makes it especially useful in modes which feature all three detections, though due to its rather low duration it is not the best option.
• There are multiple towers that cannot be affected by its Firework Buff and multiple towers which can generate multiple fireworks at once, but this list does not contain information on the detection buff it provides. The list below will only include information on the main attack, though if it does actually generate fireworks it will be listed. For example, the Pursuit will not be listed as partial due to its missiles not creating fireworks:

  • Other languages, such as German, can have tower names which exceed 18 characters.
