God of War Grendel Boss Guide - How to Defeat Grendel of the Ashes and Frost

Our complete God of War walkthrough includes collectible locations, puzzle solutions, Valkyrie boss fights, armor upgrades, and much more.

Grendel of the Ashes and Grendel of the Frost are two boss characters you’re going to be going up against in God of War, in the Tyr’s Vault section of the game. In this God of War Grendel boss guide, we’ll be walking you through how to defeat the pair of bosses as smoothly as possible, pointing out weak points and powerful moves, as well as the rewards you’ll gain for defeating the pair of trolls.

If you instead need anything else on God of War, including a full story primer for everything you need to know heading into the latest game, as well as all the combat controls and combos you need to know for both Kratos and Atreus, make sure to head over to our God of War walkthrough hub.

God of War Grendel of the Ashes and Frost Boss Guide

This boss fight kicks off right after you’ve made it through the Tyr’s Vault section of God of War, so if you need help on making it through the area prior to this boss encounter, head over to our God of War Tyr’s Vault walkthrough guide. For defeating the pair of bosses however, Kratos is going to have to be quick on his feet.

God of War Grendel Boss

To begin with, only Grendel of the Ashes is active, while his partner slumbers in a corner of the area. You’ve got to use this time wisely, and lay into Grendel of the Ashes with as many attack as possible, as quickly as possible, before his other half awakens. Even when Grendel of the Frost awakens however, we’d still recommend sticking to Grendel of the Ashes, even though his other half will begin to heal him.

Your objective here with Kratos is to basically defeat Grendel of the Ashes as quickly as possible, before turning your attention to Grendel of the Frost. Don’t worry about the former boss getting back up after he’s defeated however, as he’ll stay down for good once Kratos has defeated him.

You’ll find that all your attacks to Grendel of the Ashes have actually damaged his other half as well in the process, so the second boss has dramatically reduced health by the time you turn your attention to him. All you need to do is finish him off, execution style or with the Blades of Chaos, and Kratos and Atreus will be free to proceed.

For making it through this tough battle, you’ll be rewarded with 8567 XP, a Chaos Flame which can be used to upgrade the Blades of Chaos, three Hardened Svartalheim Steel, over 5000 Hacksilver, and a Tartarus Rage Heavy Runic attack.

We might be all wrapped up with this in depth God of War guide on how to defeat both Grendel of the Ashes and Grendel of the Frost, but head over to our Niflheim Cipher Pieces guide, or our Muspelheim Cipher Pieces guide for info on how to gain access to brand new realms. We've also got guides to find all Idunn Apples and Horns of Blood Mead.
