TwrIcon BGem "No man should have this power"
The Blazing Gem is a premium Magic Tower in Kingdom Rush: Vengeance, and costs $4.99. It focuses an intense laser beam onto an enemy that deals more damage the longer it's locked on a single enemy.


Fueled by the dark magic of Vez'nan's acolytes, The Obelisk's power increases the longer it locks onto a target, able to roast the toughest of enemies in a few seconds.

For every 1.25 seconds spent locked onto an enemy, the Blazing Gem's damage increases, to 2x the listed value and then 3x (4x with Gem of Amplification). There‘s no limit to the damage this tower can do.

Unlike other towers, the Blazing Gem does not automatically the enemy within range that is nearest to the exist; instead, it targets the enemy that is furthest from the exit, and will only switch targets when the current one dies or moves out of range. It has a 1.5 second cooldown between lockdown. The time it takes for changing targets varies from 0.5 to 1.5 seconds.

This tower functions similarly to the Wild Magus from Origins as it is a magic tower that increases damage the longer it holds onto an enemy, and with both Destructo-Ray and Unstable Power it also gains a similar functionality to Eldritch Doom by killing an enemy and damaging those around it.

The Destructo-Ray is also similar to the Arcane Wizard's Death Ray, with its ability to instant kill any units, leaving behind nothing but black dust.

The Blazing Gem is excellent at killing high HP or high physical defense enemies. Gem of Amplification makes it even easier to take down tanks, and Destructo-Ray is good at getting rid of tanky threats in a snap of a finger. Despite the Blazing Gem being an amazing tank killer, it has a couple major flaws. One flaw is the fact the tower doesn‘t have good range, making it easy for tanks to get away. However, this problem is solved by using barrack towers like Dark Knights or Orcs. Also, the Blazing Gem has awful crowd control, as it targets the enemy furthest from the exit and deals initially weak damage. Unstable Power isn’t useful against higher health units later on, so use artillery to support crowd control. However, Unstable Power is good at weakening enemies, making it easy for Shadow Archers or Elite Harassers to kill weakened enemies.
