Upgrading Equipment

[Tuxedomask]

Thanks, i got Harpoon from the market that is fine for the moment. The real problem is the armor and the other equipment =/. I guess i will try selling my shards.

I, too, recently just started playing the game. You should be able to do level 20 leves now, so you should exclusively stick to that for gil.

Also, sell any "trash" you find. You can generally sell it for double the vendor price, maybe even more.

This is a very good site that shows Vendor Prices and which category they are under so you can easily check prices.

I've made about 400k just selling vendor junk and shards.

Another tip to save some gil is - always have someone repair gear for you.
NPCs sell Grade 1-5 matter which is used to repair gear at their respective levels.

NPC Grade sell prices:
Grade 1 = 100
Grade 2 = 600
Grade 3 = 1500
Grade 4 = 2800
Grade 5 = 4500
ie. Let's say you want a level 6 Spear repaired. It requires Grade 1 Matter.. so put it up for repairs for 200gil.

Find out which Grade is needed to repair which gear, and basically double up on it, seek repair, and stand next to the Ul'dah repair NPC, and it will generally be repaired within 5 minutes.

It's ALWAYS cheaper to get repairs from players, even with being generous and doubling up on Grade Matter.

Good luck to ya!
