Harrow Systems Blueprint: Drop sources, locations, and probabilities
Tips
There are many ways to get Harrow Systems Blueprint in Warframe,
but my recommendation for optimal efficiency would be to
try one of these missions (in this order):
- Kuva Fortress/Taveuni : It's a Survival mission (level 32-37). The item is dropped on rotation C (12.00%).
- Phobos/Memphis : It's a Defection mission (level 15-25). The item is dropped on rotations B (6.00%) and C (15.00%).
- Saturn/Caracol : It's a Defection mission (level 26-36). The item is dropped on rotations B (6.00%) and C (15.00%).
- Neptune/Yursa : It's a Defection mission (level 30-40). The item is dropped on rotations B (6.00%) and C (15.00%).

Warframe Rotations Explained
- Survival: One reward every 5 minutes, following this pattern: AABC.
Rotation A at 5 and 10 minutes, B at 15 minutes, C at 20 minutes, etc. Then it starts all over again (25min is rotation A).
