Rare spectrum gem damage

Rare spectrum gem is 5000 on a solar trans blade

The Rare Spectrum Gem grants the user +500 spectrum damage, meaning that nothing except spectrum defense will block it, and bosses which have spectrum defense take 1/10 of additional elemental damage. This can be counteracted by using a Solar Weapon due to the Attack Gem boost on all 3 Solar weapons. It sells for Gp-icon.png 500,000, but the combined cost of the nine gems needed to forge is Gp-icon.png 9,000,000 (the combined sell value being Gp-icon.png 4,500,000). Also, if you want to skip the forging time, you'll need Gp-icon.png 11,400,000.

  1. Forge together one +400 fire attack gem, one +750 fire outdoor gem, and one +750 fire indoor gem.
  2. Forge together one +400 ice attack gem, one +750 ice outdoor gem, and one +750 ice indoor gem.
  3. Forge together one +400 water attack gem, one +750 water outdoor gem, and one +750 water indoor gem.

When used in a solar transport energy blade, the beam keeps on changing color.

If it is put in a normal weapon, the hit effect is similar to that of the Lady Finger. When it stabs, it has the Infinity Blade's stab animation.

It will not work if the fire, ice and water gems are not rare +500 gems or they were put in the wrong order. If so, the resulting gem will not be a Spectrum.

If 3 Rare Spectrum Gems are forged, the result is a Rare Spectrum Gem with +1000 damage, or 10000 damage on a solar-trans blade (right). The forging of the resulting plus +1000 gem with two subsequent +500 gems results in another +250 per forge (eg. 1000+500+500 >> 1250)(bottom-right).

Both the Rare Spectrum Gem and the Rare Darkfire Gem have a 10% successful effectiveness against bosses with Spectrum defense. The Solar Transport Energy blades provide damage amplification that helps counteract this, rendering them very effective against the Deathless for +1000 Spectrum or Darkfire gem.


  • In Infinity Blade III, on the 10th of December 2015, in commemoration of the fifth anniversary of Infinity Blade, a ClashMob that rewarded a Rare Spectrum Gem was held.
