I'm looking to make a 20th level character incorporating levels or arcane archer. This is a strictly core-only campaign. The GM said we have unlimited gold to purchase any and every core-only item we want. I'm feeling pretty overwhelmed in creating this character. Do I go fighter/wizard/arcane archer, ranger/wizard/aa, bard/aa? We have a party with a melee tank character, a wizard, and a cleric. I'm aiming to be the ranged DPS. Any advice?
