I wrote this guide because of the number of poeple who've posted where they can get these things, so here it is, in the guide section

Ok first, to get materials, you can get them in-game at flaris centre from a wide selection of npc's.
Second, you get weapons from "(Shield 2) Ludo" right near the weapons, upgrading and shield guy in central flaris, or in the webshop (read No 3).
Thirdly, sunstones. You get them in the webshop (must have enough money or system takes all ur money and u get nothing, so add it all up BEFORE you buy) or get them in-game at Juria, flaris bank store owner .
Moonstones are also sold at Juria for 1m each .

Just a little help for new people so hope this helps
