Modify your users hp based on permission groups or individually. Great for RPG servers!
This plugin is for those seeking for a plugin that can modify users max health but couldnt find one that suit their needs yet, just like me!
SoftDependency: Vault. Only needed if trying to use the GUI feature or trying to use the per group HP system.
For the GUI feature you may also need an economy plugin, and for the per group HP system you may need a permissions plugin.

Groups based max HP (ie: user: 10HP, admins: 20HP)
Individually based HP
HP set (player) command for setting a players max health independently of their group
HP add (player) command for adding hp to a players max health independently of their group
Check and correct a players HP to the HP specified in config on join, with ability to disable this feature
HP GUI for buying or selling HP (needs Vault)
Price formulas for increasing prices on proportion to players' HP
Consumables! (Items your players can consume for modyfing their HP)
HP permission checking - Set a player's HP by giving them a "healthpower.amount.X" permission

Commands:

-/HP - Opens the GUI (if enabled, otherwise shows help) (Also /hp gui to open the GUI)
-/HP help - Shows this list of commands
-/HP version - Show the plugin's current version
-/HP reload - Reloads the plugin's files
-/HP set (player) (HP) - Sets a player's max health to the specified
-/HP add (player) (HP) - Adds HP to a player's max health
-/HP gui - Opens the health buy GUI.
-/HP consumable get (name) - Gets a consumable by its name in the file.
-/HP consumable set (name) (add/set (refers to the health operation, either add hearts or set hearts) (amount of hearts)) - Sets a new consumable in the consumables file.
-/HP clear (player) - Clears a player's name from the HP file.
-/HP clearAll - Clears every player's name from the HP file.
-/HP check (player) - Checks and corrects a player's HP.
