Toolhouse/Runic Toolhouse

[Enola]

What are they and how do they work? As I understand, the toolhouse holds a lot of charges for every tool out there (so I guess the runic toolhouse works for runic tools, as in tools that create stronger items?), but does it come precharged? Or do I need to charge it with tools I buy, get as reward or make myself? And what's the difference between the (runic) toolhouse you get as a donation reward and the one you can craft?

[Harabakc]

They're resource keys for tools.

Think about the spell caster keys that you put tools and runic tools in.

They're empty, you combine them yourself.
