You can press the big button over the anvil to get some explanations on the mechanics, such as how the anvil works. The game gives you plenty of trinkets, but you have to use them conservatively. For example, if the enemy will die with only 1 trinket equipped, it's better to unequip all others so you'll conserve charges on them. It might take a little practice though! Also be sure to read the enemy passives, because some of them will take charges from your trinkets. Thanks for playing !
