Yep, we're going the big-time cheating route here, but frankly, there's a good reason to do so. Wolcen utilizes a rather odd design where you don't actually need all those potions taking up spots in your inventory. You only need two in your hot-bar.
The ones in your inventory are just taking up space and don't help you at all. Instead, the potions you have equipped recharge as you kill monsters. With the Infinite Potions mod installed, it cuts out the middle man and makes item management much simpler.
