- Forge together three +400 fire attack gems.
- Forge together three +400 ice attack gems.
- Forge together three +400 water attack gems.
- You should now have three rare elemental attack gems. Forge them together in this order: Fire - Ice - Water
It will not work if the fire, ice and water gems are not rare or the gems were put in the wrong order. If so, the end 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. The forging of the resulting plus +1000 gem with two subsequent +500 gems results in another +250 per forge (eg. 1000+500+500 >> 1250).
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 pin this perfectly, rendering them very effective against the Deathless for +1000 Spectrum or Darkfire gems.
