Sentinel Hammer

The Sentinel Hammer is a weapon introduced in The Ancient Gods - Part Two DLC for Doom Eternal. It is a large energy-based warhammer of Sentinel origin which serves as a replacement for the Crucible from the base game.

The hammer originally belonged to Commander Valen who gives it to the Doom Slayer during his pilgrimage to the World Spear.

Uses
Using the Sentinel Hammer launches the Doom Slayer momentarily up into the air before he comes crashing down, slamming the hammer into the ground and causing a shockwave around the point of impact. Enemies caught in the shockwave are temporarily stunned and drop resources. Enemies frozen by ice grenades drop additional health during this time, while enemies who've been set on fire by either the Meat Hook or flame belch drop additional health.

The Sentinel Hammer is recharged by destroying enemy weakpoints or by performing glory kills. Each level in the DLC also has tokens which can be picked up to instantly refill the Sentinel Hammer's charge.

Upgrades
The Sentinel Hammer can be upgraded by completing the first stage of each of the three escalation encounters in the DLC. As the first stage of each escalation encounter is mandatory, the hammer will be full upgraded by the end of the DLC.

Completing the escalation encounter on the World Spear unlocks an ammo upgrade which causes enemies to drop more ammunition when affected by the Sentinel Hammer. The escalation encounter on Earth Reclaimed provides the Fire and Ice boost which causes flaming enemies to drop more armor and frozen enemies to drop more health.
