Maisner is the second most important NPC in Hobo: Tough Life after Master Hobo. Master Hobo can be found in the southwestern part of Zikzov. He not only provides you with most of your crafting recipes, but also provides you with tons of survival tips. Master Hobo is one of the most important NPCs in the game.

Knowing the recipes will help you get the required items much earlier in the game, so when you come to an NPC who teaches you the recipe, you will already have all the necessary ingredients to work with and get cracking on that crafting.
