Can you add an option to not have the Catalyst consumed?
Thinking about making an item that activates all summons.

Thanks for the suggestion!

Example usage added to the main README
".setConsumeCatalyst(false)"

Catalyst isn't consumed, but right now it only grabs the first recipe with a matching catalyst without checking the ingredients so having 2 recipes with the same catalyst won't work. Will fix

Added support for multiple summonings using the same catalyst.
The altar will pick a random summoning if multiple match the ingredients available + reagent
