Onyx Amulet & Primordial Stones
Using Freezing Ice Stone, Desirous Blood Stone and Prophetic Twilight Stone is the best single target combination for demonology by 1-2% depending on your current rings and Onyx Amulet item level.
For any AoE, the ring is currently a downgrade for most people. Sim yourself for an accurate comparison for your character.
Tier Set
The 10.1 tier set is very good both numerically and playstyle wise.
- 2pc - Demonbolt deals 15% additional damage. Consuming a Demonic Core reduces the cooldown of Grimoire: Felguard by 1 second.
- 4pc - Grimoire: Felguard damage increased by 20%. While Grimoire: Felguard is active, all of your demons deal 20% additional damage.
The tier set "forces" you to pick up Grimoire: Felguard, but in 99% of cases, it was a default talent, so it doesn't feel like a hindrance. The tier set amplifies both demonbolt focused builds (Fel covenant/sacrificed souls) but also more pet damage focused builds (Antoran Armaments/Immutable hatred/Gul'dan's Ambition).
With a decent level of haste and good demonic core management, the Grimoire: Felguard cooldown is brought down to 1:30, which makes it line up with the newly buffed Reign of Tyranny Tyrant. This gives you a very powerful single target and cleave damage profile every 1.5 minutes and an even bigger one every 3 minutes if you choose to pick Nether Portal and Gul'dan's Ambition.

- Spoils of Neltharus
