Hell, you could go the path of exile route too. Make all buffs toggles that reserve their cost from your mana pool. Have four buffs that, altogether, consume about 400 mp to cast? They're now permanently enabled until you disconnect or die, and that 400 mp is reserved from your maximum pool.
Nebulites sucked. Anything below A-tier was literally garbage, and the only thing anyone used at A-tier was decent sharp eyes, 20% boss and 4% allstat. Not a really good "came at great cost" argument.
Here is a list of most, if not all, damage skins that exist. Do keep in mind that only some of them are available at any given point, and there are different ways of getting them.
Some come from quests or events, but most come from random-drop boxes in the cash shop.
These are the ones I've collected over the course of about three years plus change:
Most, if not all, of them are from events over that time period. I think I only bought one of the 30 I have saved.
You cannot have the same thing on all three lines. You can't have three lines of item drop or anything else.
The rewards from that quest are absolutely not worth it. The empress's might quest itself only gives you a beginner-tab passive that allows you to equip gear up to ten levels above your own, which in the present state of things is objectively worthless. Past that is a series of quests from whichever chief knight matches your own class's archetype to get levels 1-5 of an old pre-revamp cygnus knight skill.
Personal opinion: stop now, put your time into something else.
