well.. you got 1k fg... you can buy lots of stuffs..
you should buy now weapons for your lvl... so buy a lvl 15 sword... and upgrade it each 10 lvl..
so it will be lvl 15/25/35/45/55
get heavy armor (Plate mail or Chain mail) with Enhanced Effect or strength or dexterity...
and get a charm with strenght or dexterity..
but remember..
try to have 100-120 dexterity when you are lvl 45+...
so imo you can put some points now in dexterity and try to get itens with strg...
or you put the stats on strenght and buy some dexterity itens....
if you find a item on market that you like and dont know if it really worth it, try asking for help here:
