|This is a mission in Minecraft Dungeons. It harbors the Arch-Illager and Heart of Ender boss.|
|— In-game story|
The Arch-Illager has fled to the Obsidian Pinnacle, a place full of statues, narrow ramparts, Illagers, etc. To get from one section to another, heroes need to jump between different areas of the broken rampart with the help of spring platforms, which also kills companions while jumping to a new section. They are likely to land right in the middle of a horde of mobs.
Several Redstone Golems also reside at the top of the Obsidian Pinnacle. Once the heroes have fought their way through the hordes of Illagers, they can reach the top of the Obsidian Pinnacle and come face-to-face with the Arch-Illager. After defeating him and his creations, heroes encounter the last boss of the game, the Heart of Ender. At last, the Heart of Ender and the Arch-Illager's evil reign is ended by the heroes.
The Obsidian Pinnacle appears to be the ramparts of Highblock Halls. It has a lot of narrow passageways that often lead to dead ends. Spring platforms appear often as there are many gaps in the level. There is a small indoor portion of the mission that resembles Highblock Halls but is more worn down and much smaller. Illagers and Redstone Golems appear in large numbers here and are the only mobs including Endermen that can spawn in this mission. At the pinnacle of the ramparts is where the Arch-Illager is hiding from the hero.

- In the preview image for Obsidian Pinnacle on the menu, a Redstone Cube can be seen among some other enemies. However, redstone cubes don't actually spawn in the mission itself.
- This is the only location that harbors two different final bosses, the Arch-Illager and the Heart of Ender.
- There's an obsidian chest and a fancy chest in the rune room which is located near the end of the indoor portion.
- The intelligible noises in the beginning cutscene is actually a reversed phrase saying " Fight your way out, endless of heart".
