Act 3 and Cruel Mode - Transitioning to Endgame
As you move into Act 3 and onward into Cruel Mode, your Witch Minion build starts to show its true potential. This phase is where your minions become a force to be reckoned with, thanks to better gear and more advanced abilities.
Act 3: Your Build Starts to Shine
By Act 3, your Witch should be using more powerful minions, such as Skeletal Arsonist and Raging Spirits, to deal with the tougher enemies. You’ll unlock a third gem slot with the use of a Lesser Jeweller’s Orb, and this is where you can start socketing Feeding Frenzy to boost the effectiveness of your minions.
Also, replace Skeletal Snipers with Skeletal Arsonists. These minions pack more of a punch, and combining them with Martial Tempo and Fire Penetration will give you an edge, especially against bosses.
Cruel Mode: Preparing for Endgame
In Cruel Mode, your Witch Minion build comes into its own. You should unlock Skeletal Storm Mage, which applies the Shock status to enemies, making them take more damage. Equip Skeletal Cleric for resurrecting your fallen minions and healing them during combat.
At this stage, make sure you’re upgrading your gear to enhance your minions’ survivability. Use Immolate on Raging Spirit to increase your damage potential, replacing Fire Penetration.
