Absolutley must have for your DnD 5e adventures! The quality of art and content of the Pdf are amazing! I can tell that so much work whent into detail, it feels like an apple product in terms of quality. They also extensively tested it for 2 years using monte-carlo simulations to make sure that the upgrades were not over powered. At first glance the upgrades look balanced. Adding game mechanics for upgrading weapons and armor, gives your players something to spend their earned cash on and really creates more depth to your DnD games. Look very much forward to the upcoming alchemy almanac!!!
