HOW TO GET PLATINUM AND ETERNAL ORBS?
Platinum can be obtained from three sources:
- The 12th Bounty rewards you a treasure chest that contains 150 Platinum. In a 28 days cycle, you can earn 4200+ Platinum per month if you complete all 12 Bounties daily.
- The daily Kill of the Day reward for the week might be source of Platinum. Depends how often these are on rotation. In the rotation shown below: That’s 10,000 Platinum in one week.
- The less attractive route to obtaining Platinum is the in-game shop — for Eternal Orb.
Eternal Orb can be purchased for real money. The UI for purchasing Eternal Orb is not currently available in Diablo Immortal technical alpha.
