You can get fragments from all the monsters at Torment, and using it to craft your hunter equipment to make them even stronger. Fragment has very low chance to drop, so be patient.
- Ancient Fragment drop at T1 and T2 (T2 for higher chance)
- Primal Fragment drop at T2 and T3 (T3 for higher chance)
T1 monsters also dropped Primal Fragment but with very very very low chance.
