How to get Great Martyr's Blade
- From Gloomshade Grove Beacon, go northwest to the hole in the castle wall. Alternate: Grove-side Holding Cells well.
- Open the cell gate with the wall button.
- Clear the next room, break the boxes in the corner, and take the blade from the table or slab.
When to use it
- Balance Patch 1 added +20% attack; Week 1 pushed it again because the first buff missed the live build.
- Best default heavy if you do not want Obsidian Hammer's full commitment.
Before you leave
- If the room looks empty, you have not broken the corner boxes.
