Alright, I intend to start DMing here in a few weeks, but I don't plan to play straight pathfinder. I have a few changes to the game that I want to implement but need some help doing so. The main change being that my world has no magic except that which is provided by the gods.
When it comes to character selection i know this will limit my players can chose and some will be tempted to become a monk or paladin and while I won't outright tell them they can't i will advise against it.
Now that there's no magic in the world (for the most part) at the end of my first major quest i will introduce "gems" to my players each getting 2. These allow any character to do magic, but only specific spells which are a part of the gem, and instead of having a limit per day they will cost the health of the player.
Here's a list of the gems and a simple explanation of each:
Fire: allows the user to create and control fire.
Water: Allows the user to control, locate, and freeze water.
Earth: allows the user to control the earth beneath their feet, and the wildlife/plants around them.
Air: allows the user to control and purify the air around them. Even to a molecular level.
Electricity: allows the user to create electrical surges and control the lightning during a thunderstorm.
Telekinesis: allows user to control small objects near them. (Launching as a projectile is still relatively complicated and I may scrap the idea of this one all together combining it with the next and finding a replacement.)
Telepathy: allows user to be able to read minds, and feelings as well as pushing their own emotions onto others. (Such as confidence to an ally to give them a boost, or fear to an enemy)
Buff: i originally had 12 gems but decided to put a few of them together all into this gem.
Just before the buff gem was made i came up with the concept of leveling up the gems, and adding an additional called gem mastery to roll for in character creation. To give you an idea of what I mean ill show you the buff gem which is done up to level 5 and the fire gem which i only have the first 3 spells for.

First of all i would like to ask if you think the concept of unlimited casting at a cost of health can work, and secondly I need some ideas of how to scale the spells so they are useful throughout, without being overpowered right away, and make the health drain for using the spell not instantly kill an early level, but not be a loss of like 1 health in later levels. (But still easier to cast as time goes on.)
Sorry for not having spoilers to make this easier to keep up with. First time posting, and posting from ipad.
