The following are all homebrew rules for this game. I am open to ideas and discussing any of the ones posted.
Healing potions heal max.
If you find a game token keep it secret, if you share how to get one with anyone for any reason all your tokens will be striped.
Any and all spells require a crystal as a focus (ignore all other material component and focus rules) spells with a gold value material requirement need an equal value of stable Machina crystal. If the component is normally consumed so is the crystal.
Machina crystals are valuable and rarely sold for gold. Though a gold value is placed on them for game cost reasons, it's rare to be able to buy one for that amount or any amount. Do not be surprised if some places will only sell a 100gp crystal for 1000g, or not at all.
Long range teleport spells are taboo, all of them have a high chance of mishap if you have or are around any crystals on any side of the teleport, and crystals do not travel with when using them.
Crystals cannot be put into an extradimensional space or leave the plane.
