How do you create Foefire's Essence?

Reddit has discovered quite a few new weapons are available, all of them modelled after weapons that Guardians, Eles, and Mesmers can conjure. I'm specifically interested in Foefire's Essence.

The Mesmer weapons have a predicable pattern of Mystic Coins + Eldritch Scroll + Ectoplasm + Tier 6 Weapon Components. I'm wondering if such a pattern exists for the Guardian weapons and, specifically, how you create Foefire's Essence.

Solution 1:

Foefire's Essence can be created in the mystic forge by combining:

• 1 Eldritch Scroll
• 1 Gift of Light
• 70 Mystic Coins
• 250 Orichalcum Greatsword Blades
