What is this weapon?

A few weeks ago (Sept. 5, to be exact) I noticed some strange behavior while doing Kaineng Center quests with my warrior. The skin of my Icy Dragon Sword was very unstable, alternating seemingly at random between its normal appearance and that of some weapon I've never seen.

I checked all the sword variants on guildwiki, but none of those pictures match this one. It has a rather long blade with a sparkling aura similar to a stormbow. Did anyone find this sword during the Nightfall event?




Edit: Wow...don't I feel dumb. Guess it wasn't such a mystery after all.

Ritualists cast it on you..I forget the name. It changes your sword into that one for a set ammount of time.

That's a sword under the effects of Weapon of Warding.

I can't believe people are still asking this question...

You were a newbie once too.

Anyways, closed. Q was answered.
