A cauldron was no different than any other ingredient. Its size, shape, and fabric led to unique behaviors that alchemists had to account for to limit variables.
Performing already perfected concoctions was the best way to spot such differences, and Liam had the ideal tool for the task. His rank 3 venom stashes always increased, and he would never run out, so he didn't hesitate to burn it with abandon.
The silver cauldron revealed its secrets as concoctions followed. Liam didn't aim for success. He purposely engaged in practices he knew would fail to familiarize himself with all the item had to offer.
That phase ended when Liam retrieved a yellow pill from the cauldron. It was one of his usual rank 3 Poisonous Cloud pills, but it somehow felt stronger despite Liam having made no changes to the recipe.
