Non-tomestone ways to get to item level 460? Crafting?

[Jettinson]

Edenchoir is ilvl 500
Tower at Paradigm's Breach - ilvl 495 requirement - ilvl 510 gear.

Just small corrections, the final normal eden raids give artifacts that can be exchanged for 510ilv gear which is also the cheapest/gill less way to get accessories at that point if you do not plan to augment exarchic gear
The Tower gives ilv520 gear which is also a temporary replacement vs base cryptlurker gear/augmented exarchic until you augment the the tome gear.
