blood, sweat, and tears

You've spent hours and even days working on your infusions to the point where you can put every fiber of your being into it. You have a multiple of ways to gain more infusions.

• At the beginning of a long rest you can choose to stay up all night and work on an infusion. You can either work with your hammer or craft quietly. Working queitly will give you two levels of exhaustion while working with your hammer will give you one lvl of exhaustion. Working with your hammer puts your other party members at risk. All party members within 60 ft must make a perception check and if they get over 10 they wake up. If they wake up they must succeed on dc 15 dex check or go without sleeping and take a lvl of exhaustion. If they artificer stops working the party member can go back to sleep.
• Lower your hit point maximum by 10 points, going up by 5 each artificer lvl.

You can only have one extra infusion.
