The Oblivion Deathbomb is a powerful explosive added in AbyssalCraft. It is capable of destroying almost any block in the game (apart from Bedrock, End portal frames and Glowing Darkstone Bricks).
The Oblivion Deathbomb is crafted using 1 Oblivion Catalyst, 1 ODB Core, 5 blocks of Obsidian, 1 Liquid Coralium Bucket and 1 Liquid Antimatter Bucket. The 5 Obsidian blocks are placed in a "C" shape, with the ODB Core in the center, and the Oblivion Catalyst next to it, with the buckets placed on the slot over it and the slot under it (one on each place).
This block drops nothing.
Apart from wreaking havoc with a big explosion, the Oblivion Deathbomb is used to summon Sacthoth, Harbringer of Doom. After the explosion, a 19x1x19 platform will appear, where Sacthoth will spawn.
- The explosion has been altered many times through the development of AbyssalCraft, mainly due to it not being powerful enough, but also due to it sometimes crashing the game due to it needing too much computer resources.
