Ive seen on or two other flavors of the custom flare but not this particular one.

I have no idea what these particular flares would actually look like except what Thandiwe posted for the elemental versions of this one.

(Only for examples copied from Thandiwes post - Not this voucher unless its the eblade option.. lol)

Fire - Bright red and ethereal, a flame-wreathed dragon eel bursts from your vultite falchion and explodes into a bog troll!
Cold - Indigo and ethereal, an icicle-wreathed dragon eel bursts from your vultite falchion and explodes into a bog troll!
Electricity - Silvery grey and ethereal, an electricity-wreathed dragon eel bursts from your vultite falchion and explodes into a bog troll!

Looks like this:
Your voucher is of the Ghezresh Custom Flare Messaging variety and has rotating Custom Flare Messaging. Using it will give a weapon or armor that already has a Bless, Consecration, or E-Bladed flare on it the customized messaging.

Thanks for any info/assistance
