Money pouch and platinum tokens
Project Zen has an RS3-style money pouch, so you can carry cash without it taking inventory space. Shops take payment from the pouch first.
Platinum tokens are worth 10,000 coins each.
Ring of Light
The Ring of Light can send your drops straight to your bank or inventory.
Loyalty points
You earn 500 loyalty points for every full hour you play in one session. Imperial donators earn six times as many.
