How to complete the Heart of the Fist quest in Phantom Blade Zero and find the grave
The Heart of the Fist side quest in *Phantom Blade Zero* asks players to find the Iron Fist Master’s grave in the Mirrorwood and leave incense for the Iron Fiend. Completing it rewards an item needed to upgrade the Iron Gauntlets, making the short search useful for players pursuing that weapon.
The grave is beside the Burial Grounds Bell, on the eastern side of the Crimson Forest; fast travel there and interact with the large grave in the icy clearing. Soul receives the Fist Fragment: Shell, which combines with the Fist Fragment: Core earned after the first Iron Fiend fight to form the Worldbreaker Fist. This is required for Soul Tempering the Iron Gauntlets Phantom Edge.
In short
- The grave is near the Burial Grounds Bell in the Crimson Forest.
- Leaving incense gives Soul the Fist Fragment: Shell.
- Combine it with the Core to make the Worldbreaker Fist.
Explained simply
Phantom Blade Zero is an action role-playing game in which players guide Soul through fights and side quests. The Iron Gauntlets are one of his weapons, and improving them requires finding particular items during the game.
The Iron Fist Master and the Iron Fiend are figures linked to the gauntlets’ story and upgrades. The quest connects them through a grave in the Mirrorwood, while its reward is used alongside a fragment gained from an earlier fight to make the Worldbreaker Fist.
That item is needed to Soul Temper the Iron Gauntlets Phantom Edge, a process for upgrading the weapon. The grave search therefore matters to players who want to develop this set of gauntlets.
