If you want to upgrade your armor in Destiny 2, hitting Masterwork tier and getting access to all your available energy slots, then you will need to get your hands on some Enhancement Prisms.
There are a hard to get item, and will only be available from the following sources:
- Banshee-44 in the Tower
- Season Pass
- Nightfall: The Ordeal
- Dismantling Masterworked gear
Banshee-44, The Tower Gunsmith
You can purchase Enhancement Prism from Banshee-44 in the Tower, for the following resources:
- 10 Enhancement Cores
- 25 Planetary Materials
- 10,000 Glimmer
Each day, there will be two different options available for Enhancement Prisms that require different planetary materials. The 10 Enhancement cores is pretty steep, but you can earn them by doing Gunsmith bounties.
When you get to the later stages of the Season Pass, you will be able to earn some Enhancement Prisms, although it is a limited amount. You will get 3 Enhancement Prism at Rank 60 and another three at Rank 70.
Nightfall: The Ordeal
Certain Nightfall: The Ordeal difficulties can drop Enhancement Prisms upon completion.
- Hero – 1220 Power – rare drop
- Legend – 1250 Power – uncommon
- Master – 1280 Power – common
While it might seem tempting to jump into the higher Tier Nightfalls, matchmaking stops after Hero level, so you don’t have a fireteam it won’t be an option.
Breaking down Masterworked Gear
If you have moved on from previously Masterworked 2.0 armor pieces, then breaking them down will get you some Enhancement Prism. It will need to be 2.0 armor however, the old 1.0 armor won’t get you an Enhancement Prism.
