Blast is a tower in Infinitode 2. It emits a shockwave that damages and can stun enemies in its range. At higher experience levels, it gains the ability to also push enemies back when they are stunned similar to Windstorm.

Unique Characteristics

Blast has Stun duration and Quake charging speed as its Unique characteristics.

Stun duration is how long Blast stuns enemies. By default, Stun duration is 1.5 seconds and increases by 0.065 second each experience level.
Tooltip: Decreases by 25% each time the same tower stuns an enemy again, down to 0%

Quake charging speed
Tooltip: Once fully charged, the next attack is guaranteed to stun all enemies in range for ×1.5 duration. Does not ignore enemy immunity. Quakes also disable towers standing close for 2s
By default, Quake charging speed is 4.5% per second and increases by 0.15% each experience level.

Other Characteristics

Blast does not have Rotation speed; instead, it attacks all enemies within its range.

Each shockwave has a chance to stun each enemy, completely stopping them for a few seconds. The maximum Stun chance is 75%.

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

• Enemy Stun Immunity: Enemies gain stun immunity from all Blasts. This immunity decreases by 2.5% every second. Enemies lose this effect after 40 in-game seconds (on regular speed). If the enemy gets stunned while having Enemy Stun immunity, it gets refreshed instead. After 5 individual stuns, this immunity is set to 100% and will no longer decrease.
• Enemy Tower Immunity: Chance of getting stunned from that particular Blast is reduced by 25% (additive).
• Each consecutive stun is 10% shorter than the previous stun (additive).
• Net Blast Stun Chance = Stun Chance × (1 - Enemy Stun Immunity) × 0.8^{Enemy Tower Immunity}_.

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

The AoE damage is based on distance from the Blast. Enemies closer to the Blast take more damage.

Stun chance is not classed as a unique characteristic, which means it can be improved with bonus PWR and upgrade levels.

Abilities

LV	Ability	Description
4/7	Heavy shell	Attack speed ×0.8, damage ×1.68, chance to stun ×1.1
	Fast mechanism	Attack speed ×1.2
	Sonic wave	Stun duration ×1.2, triggers a quake as soon as it is ready and stuns 1 random enemy outside Blast's range
10	Stopping force	Throws back each enemy (just once) for 0.5 tiles with 10% chance Upgrades with the tower
20	Ultimate	Enemies receive a Vulnerability debuff for 2s after being thrown back, which makes them receive +15% damage.
	Powerful	PWR ×1.1

Stopping force: Occasionally, when stunning enemies, Blast will push them back toward the portal but can no longer do so. Distance increases by 0.1 each upgrade level and caps at 1.5 tiles.

Heavy shell: Becomes 12% less efficient at stunning but gets ~34.4% more DPS.

Ultimate: Vulnerability increases by about 5.5% each upgrade level.

Strategy

Blast is mostly a support tower but can help offensively. Its ability to stun makes it a must, especially for late-game waves. Use in conjunction with Freezing; it will give attacking towers the maximum amount of time to attack enemies. The stun also boosts Splash's Rifled barrels ability since stunned enemies move at 0 Tiles/s.

While Blast can damage enemies, avoid using it as a primary tower. It only does decently against Regular and Armored, which take 100% and 150% damage respectively. Every other enemy takes 25% or 50% damage from Blast, with air enemies completely surpassing it.

Place towers away from Blast; the new Quake mechanic causes Blast to disable towers in a 1-tile radius.

Place Blast on Attack speed, Range, or Power tiles. Attack speed allows Blast more chances to trigger stuns, Range allows Blast to stun more enemies with one shockwave, and Power boosts Stun chance and Attack speed. Avoid Damage tiles since they aren't what Blast is for.

For abilities, get Fast mechanism and Heavy shell/Sonic wave based on how far Blast is from the portal. Fast mechanism is a must, allowing for more stuns and throwbacks. If Blast is closer to the portal, get Sonic wave; otherwise, get Heavy shell. While Heavy shell does reduce Blast's efficiency to stun, it is better than Sonic wave since Sonic wave can waste Quake potential at such a distance.

ADVINAS Introduction

ADVINAS: You will love the new tower called Blast.
ADVINAS: It was specially designed to stun the nearest enemies and give extra time for other towers to deal with them.
ADVINAS: Not so good in damage but can easily defeat the new Armored enemies.

Trivia

• While the tower base is a regular pentagon, the shell is not.
• This is the third tower introduced with a new enemy type, the first two being Freezing with Fast and Antiair with Heli.
• This tower used to have the least number of 100% strengths, with only one for bosses. It is now tied with Antiair.
  • This was the first tower to not have 100% or 150% effectiveness against Regular (but could still attack it).
  • This is also the only tower with four 25% strengths.
    • This is the only tower to have a 25% effectiveness against Toxic.
• This is one of four attacking towers that has an AoE attack without any abilities. Freezing's mechanics also work in AoE fashion.
• Blast along with Gauss are the only towers that can apply the 'Stunned' debuff on enemies.
• Blast is the only tower that can apply the Throwback effect debuff on enemies.
  • It can throw back enemies that have passed it, which makes no sense.
