D&D help for a newbie: how to spend my money?
i'm beginning an adventure at 6th level and i'm not very expert of the game, so i was wondering if any of you could help me:
i've done about everything but i really have no idea on how to spend my money:
the DM told us we start at 18000 gold, and i have to spend them.

My class is a homebrew class:
it's a mainly fighting class with some abilities which let him go ghostform, enpower his weapon (but i get that at 7th level, argh) and something more.
Plus, it has a very nice ability called Spiritbolt: sacrificing hp he can throw rays which deal Force damage.
the key stat for many of his ability is Cha, Con is useful because many of his abilities drain hp (it has d12 HD)...
he's proficient with simple weapons+1martial of choice, light shields and medium armor

ok, now that i've given you some sort of basis, can someone please help me spend my 18000gp ?
i think i need a weapon, armor, magic objects
Thank you in advance.

if you wanna read the whole class here's the link, but i gave you the basis i think
