I don't know if this mod has supports for PyroTech & Kitsu's ForgeCraft. There are tools in these 2 mods where PyroTech's level is only flints and stone age while Kitsu's is on Iron level and higher level.

You could try add limitation to the level of forging weapons.. for example, You want to try forge an Iron tool but you don't have enough experiences to try it. this should give you the entirely ideal.

I am not familiar with either of these mods. How does "forging" work in them? Is it something like an anvil, or is it some in world interaction.

Kitsu's Forgecraft has full interaction with forging tools... just like how a real forger would do in real life.
There are tutorials of how they works... you can watch below:

Pyrotech: https://www.curseforge.com/minecraft/mc-mods/pyrotech
it has better explanation for Pyrotech than my own explanation. It'll tell you everything you need to know if you read and examine carefully.

I hope these links will help you get more familiar with these 2 mods.
