What Drops Elemental Sword/Other Rares

What drops Max Elemental Swords (Besides Monolithes)? And what is one of the most common places they drop? I heard they drop from some enemies in GW:EN like Wind Riders and some other guys but i didnt get one yet so could you guys tell me what enemy drops Elemental Swords the Most in GW:EN?

Now onto the other Rares like Crystalline Swords do they drop in GW:EN because almost every rare drops in GW:EN aka Dwarven Axes and Tribal Axes are common there.

Crystalines drop in FoW reward chest (one by forgemaster when you do that one quest), Hall of Heroes chest drop, not sure where else, I doubt they drop anywhere, just chest drops

Yah but someone said they dropped in EoTN idk where though and not just the dungeon chests but from a monster not sure who though ;/

Max elemental swords *do* drop randomly in GWEN areas - I know because that's where I got mine, in Magus Stones, from either a Krait or Wind Rider, can't remember which.

I got my Ele sword out of the end chest from the ooze pit. it came as a shocking 15^50 +30. i sold it to fund capping all the elites in elona and tyria on my sin.

poisoned outcrops chests seem to drop ele swords. Another place to get a crystaline (purple) skin is fromt he Kilroy quest in SF. Magmas shields seem to come from chests in Hell's Precipe and from chests that spawn during the Hold the Line quest in NF.
