Luxon And Kurzick Armor

If my alliance is Kurzick, is there any way I can access the Luxon armor?

I want a piece or two for my set.

Well you could get a luxon guild to give you a guest spot so you could ab on the luxon. Other than that you can rank up luxon faction in fort aspenwood, through the faction quest and slaying monsters under the luxon blessing. It'll probably take awhile if you can't ab but it shouldn't be to hard.

yes, by doing the luxon quests until you get to cavalon

If you want 15k parts you'll have to advance relatively far through the Luxon storyline (save the lux faction you get to finish 'Befriending the Luxons' before you start converting it to Jadeite, and remember that spending Lux faction will cause you to lose Kurz faction, so empty one before you build up the other). If you only want 1k parts, just get some faction (how-to already posted) and get to Cavalon, won't take long and you don't have to do 'Befriending the Luxons'.

If you are already as far as leviathen pits and dont want to get luxon factions, just wait until the kurzigs own the town so the armorer wil talk to you. A way to get factions relatively fast, and does not require a invite to a luxon guild (to do ab) is vanquishing the areas. you can donate it in cavalon later.

yes it's possible, and you dont even need an invite to a luxon guild...
1. spend all of your kurzick factions.
2. do the befriending the luxons quest if you havent done so already.
3. do gyala hatchery mission.
4. aquire jade shards and other required materials and gold.
5. make sure you temporarily have more luxon factions than kurzick and talk to the armorer in leviathan pits.

if you just want regular armor skip step 3.

For the 15k versions don't you need at least R1 luxon or kurz? Think that was in the update that changed all armors to 1k instead of 1.5k.

I didn't need to have a Kurzick rank when I got my 15k Kurzick top on my first Elementalist, so I don't think so.
