Hello, new player here!
Im a lvl 4 Half-Orc Barbarian Archtype Invulnerable Rager.
I have 6,000 gold to play with.
No item can be worth more than 3000gp.
What should I spend my money on?Thank you !
+1 Armor
+1 Cloak of ResistanceMW Weapon
Consumables
Upgrading your Cloak of Resistance should always be the first thing you spend money on, regardless of character.
After that, it's down to cost, and what you think is best. Do you want more AC? Upgrade your armor. Do you want to hit things more often/do more damage? Upgrade your weapon. As a Barbarian, you'll want to get a Furious weapon as soon as you can afford the enchantment.
After that, upgrade your stats. STR (or DEX if you're DEX based...probably not), CON (only if you can afford it, so generally only at later levels), INT/WIS/CHA (only if they're your casting stat, otherwise only upgrade WIS for higher Will save if you can afford it easily late game).
At that point, you can start taking a look at all of the other interesting little items that help out here and there, like certain Ioun Stones.
Consumables to keep in mind: oils of magic and bless weapon, potions of enlarge person, pitching in on a clw wand for the party.
