Obsidian Igniter is a light mod that only add two items: Obsidian Igniter and Obsidian Shard.
Obsidian Igniter is a kind of "Flint and Steel" that can ignite block with a chance. The chance is 5% by default.
Obsidian Shard is a kind of material that is used to craft Obsidian Igniter.
This mod is designed for my modpack and I think it is useless for a normal "player". No one will like a random Flint and Steel if he can use a normal Flint and Steel.
