Pathfinder Online's Alpha 7 run will earn 5,000 XP per hour (in order to help them test more things), the latest devblog warns that things will get decidedly harder once gameplay starts after Early Enrollment. At that point players will face a "cold start," beginning the game with only simple peasant clothes, a club, and 1,000 XP to spend on initial feats. Everything else, from feats to gear to cash, will grow from that.
The devblog also details the player-driven economy; by design, nearly everything characters use will be player-crafted. Mobs will drop only starter equipment, coin, salvage, or -- the rarest and most valuable -- recipes. Players can only upgrade gear past the starter level through crafting, and gear can be crafted with certain key words that add bonuses when combined with specific slotted feats.
