Deals damage to all enemies within its attack radius at a slow speed with a chance to stun them, preventing them from moving for a bit. Does not fire projectiles.

Unique Characteristics

Blast has "Stun duration" as its Unique Characteristics.

Stun duration - The duration of the stun.

Leveling up the tower with experience increases Stun Duration.

Stun Duration = 1.5 + 0.065 / Tower Experience Level

Other Features

Blast does not have Projectile Speed or Rotation Speed characteristics, instead it attacks all enemies within its "Range" stat instantly.

Each attack has a (Stun Chance) % to Stun each enemy, completely stopping them for a (Stun Duration) seconds. [Max: 75%]

If an enemy gets stunned, it gains both Enemy Stun Immunity and Enemy Tower Immunity (from the Blast Tower that stunned it) buffs.

• Enemy Stun Immunity: Enemies gain 100% stun immunity from all Blast Towers. This immunity decreases by 2.5% every second. (Loses its effect after 40 seconds of not getting stunned) . If the enemy gets stunned while having Enemy Stun immunity, it gets refreshed instead. After 5 stuns, this immunity is set to 100% and will no longer decrease.

• Enemy Tower Immunity: Chance of getting stunned from that particular Blast Tower is reduced by 80% (20% of its stun chance). Multiple of these stack.
• Each consecutive stun is 10% shorter than the first stun (100%, 90%, 80%...).

• Net Blast Stun Chance = ("Stun Chance" stat) * (1 - Enemy Stun Immunity) * 0.8^{Enemy Tower Immunity}_.

Each enemy can be thrown back no more than 3 times. This also includes Windstorm.

The area of effect damage is based on distance varying from 0 (at the edge of Blast "attack range") to "Attack" (at the center of Blast Tower). Enemies closer to the tower take more damage where as enemies far away from the tower take less damage.

Stun Chance is not a unique characteristics, which means it can be improved with Power and Upgrade Levels, whereas Stun Duration is a unique characteristics which can only be improved with Experience Levels and the Sonic wave ability.

Abilities:

Ability	Description
Heavy shell	Attack speed x 0.8, damage x 1.8, chance to stun x 1.1
Fast mechanism	Attack speed x 1.2
Sonic wave	Stun duration x 1.2
Stopping force	Throws back each enemy (just once) for 0.5 tile with 10% chance [Upgrades with the tower] (unlocks at 10th level)
Ultimate	Enemies receive 150% damage while being thrown back. [Upgrades with the tower] (Level 20 required)
Powerful	PWR x 1.1 (multiplies the Power stat by x1.1)

Stopping force - Enemies will be pushed back 1 tile and they cannot be pushed back from that Blast Tower anymore. Other Blast towers can still push the enemy back.

Enemies immune to Blast (Heli and Jet) are not affected by this ability.

Heavy Shell - The x1.1 stun chance multiplies stun chance value by 1.1 not adding 10% more stun chance. Average Stun Chance is reduce by 12% (0.8 x 1.1 = 0.88) and Average DPS of tower is increased by 40% (0.8 x 1.75)

Stopping force - The distance scales with upgrade levels which is 0.5 + 0.1/upgrade level - Max: 1.5 tiles

Ultimate - The bonus damage scales with upgrade levels which is 150% + 15%/upgrade level - Max: 300% damage

Strategy

Blast Tower's unique ability to stun makes it a must have for your defenses. Use in conjunction with Freezing Tower, it will give attacking tower the maximum amount of time to attack enemies within its range.

The stun boosts Splash's Rifiled Barrels since stunned enemies move at 0 Tiles/s.

Despite the fact that Blast Tower can damage enemies, avoid using Blast Tower for damage. It only does well against Armored enemies and not against all other enemies since it only deals 25%/50% damage to them. Blast Tower's damage is reduced if the enemy is far from the Blast Tower.

Be careful about flying enemies since they are completely immune to Blast Tower.

Placing multiple Blast Towers near each other is recommended since other Blast Tower does not have Enemy Tower Immunity from the enemy yet which has a net higher chance to stun them more. Never put blast tower next to each other because of stun immunity being at its fullest.

Best tile placement: Power and Attack Speed

Power helps Blast boost its stun chance and small amount of attack speed which allows triggering more stuns at once.

Attack speed is a good alternative since it gives Blast more attacks therefore more chances to stun the enemy.

Avoid Damage tile since Blast Tower is not primarily used for damage due to dealing less damage to all other enemies except Armored enemies. It is better to use other attacking towers instead for Damage Tile

Optimal 2 Abilities: Sonic Wave, Fast Mechanism

Sonic Wave increases stun duration by 25%. This is a recommended. Having longer stuns is nice for attacking towers to focus it more. Also stun duration can only be increased through tower experience levels .

Fast Mechanism boosts its slow attack speed. This allows more attacks to be made therefore more stuns can happen. Also triggers Stopping Force more due to its 10% chance to trigger.

Heavy Shell is not a good ability to use. Blast Tower is not meant as a Damaging tower and more for stunning. This reduces average stun chance by 12% since Blast loses more 20% attack speed and gaining less 10% more stun chance (multiplicative). The damage is useless since its damage multipliers are reduced against nearly all enemies.
