I'm making a pack and having flint and steel for the nether be a gating factor for the nether, and planning for spiritfire to make some Nature's Aura items pre-nether in a more expensive manner. However, spiritfire can't be lit with any method other than flint and steel.

Describe the solution you'd like
Allow Spiritfire to be lit via fire charge.
