Is any way to get shards for free?

[Blaze The Movie Fan]

I'm training summoning, and oh boy I notice how expensive it is to get these shards. It's insane.

 

So I wanna ask is any way to get them for free? Is any monster that drops them?

 

When I train non-combat skills like crafting, smithing and fletching I like to gather everything all by myself without having to pay for it. And it works for most of these skills.

 

The only times I buy items needed is if the progress becomes tedious, which almost never happens.

 

So yeah, if you can help me that would be appreciated.

As far as I know, nope.  I do know that you can turn completed pouches back into shards, though, if that helps a little.

There are plenty of ways to gather raw cash without trading. Alchemy, monster drops, etc. Turning cash into shards is not so different from e.g. turning flax into bowstrings or hides into leather.
