I made a Radiant Blade for myself and crit it with an augment slot. Only wish that the hilts and enhancements patterns would actually drop in operations. Going to have a full set of gear 1 or 2 tiers beyond what I can make by the time something useful shows up.

Columi weapons have purple color crystals in them. Rakata have Black-Red color crystals (for Empire at least). These will be bound to your character so you cannot trade or sell them. Still haven't confirmed any source for the Magenta Adegan Crystal in order to craft the Magenta color crystals, however.

All mods, enhancements, and color crystals from raid/pvp gear already come bound to your character and thus cannot be traded or sold. So... what was the reason for not allowing armoring, hilts, and barrels to be removed again? I'm not going to play fashion judge and comment in detail on what the helm and chest items from raid sets look like, but one of the major selling points for items in this game was being able to choose your own appearance. Even after having completed operation encounters, after having acquired the higher level gear for the visible item slots, we all will face a completely unjustifiable time and money sink process just to look presentable. So I am hereby petitioning to make the Armoring, Hilts, and Barrels removable, but leave them bound to our characters. Make sure the expertise on Champion and Battlemaster gear is tied to these modifications rather than the actual item, and then let the crafters make the BoE versions to outfit the rest of your guild or sell as appropriate (assuming they can get schematics other than Armormech to drop and collect the necessary crafting materials).

I'm curious as to why people are prioritizing Creeping Terror over Crushing Darkness. With the Wrath proc you will be doing +20% damage with Crushing so the DoT portion should be ticking for more damage than Creeping, and thus you would prioritize it as the first thing cast after Death field for the most Deathmarks ticks?
