With the release of Vessel of Hatred, Diablo IV reintroduced the iconic Runeword system from Diablo II in a modern form. By pairing Runes of Ritual (action triggers that generate Offering) with Runes of Invocation (effects that consume Offering), players can bestow any character class with cross-class abilities, automated barrier defenses, and game-changing teleportation skills.
Key Takeaways
- Two-Part Runeword Formula: A functional Runeword requires exactly one Rune of Ritual + one Rune of Invocation socketed into two-socket equipment (Chest, Two-Handed Weapons, Helms).
- Offering Generation: Ritual runes generate Offering by moving, drinking potions, casting cooldowns, or suffering crowd control.
- Mercenary Reinforcement: Hired mercenaries (Subo, Raheir, Varyana, Aldkin) provide passive aura buffs and can be programmed with trigger conditions to assist during boss staggers.

Mercenary Hiring & Reinforcement Setup
- Primary Companion: HIRE Raheir the Shieldbearer for high-tier Pit pushes. His “Bastion” passive grants complete invulnerability against lethal attacks for 2 seconds with a 30-second cooldown.
- Reinforcement Trigger: ASSIGN Subo the Bounty Hunter to fire his Wire Trap whenever you cast your primary crowd-control ability, providing 100% vulnerable status uptime on elite packs.
Socketing Logistics
Runewords can only be inserted into items with two linked sockets. If your legendary or unique item dropped with one socket, visit the Jeweler in Kurast to punch an additional socket using Scatter Prisms.
