There are commands which you can use to add Strength, Damage, Crit Chance and Crit Damage:

/strength <value> (Gives an item Strength)

/damage <value> (Gives an item Damage (1 damage = 0.5 hearts))

/addcc <value> (Gives an item Crit Chance)

/addcd <value> (Gives an item Crit Damage)

/adddef <value> (Gives an item Defense )

/addhp <value> (Gives an item Health )

/addint <value> (Gives an item Intelligence )

If a hit is critical the shown damage will be in colors

You can give players extra stats by using the command:
/attribute add/remove player mana/defense/strength/critchance/critdamage value to give a player extra stats.

NOTE: These stats are saved in a file and cannot be less than 0. If you want the players to have for example less health you can decrease the base health in the config.

Growth: Gives 15 Health per level
Protection: Gives 3 Defense per level against everything
Blast Protection: Gives 4 Defense per level against explosions
Fire Protection: Gives 4 Defense per level against fire and lava
Projectile Protection: Gives 4 Defense per level against projectiles

Ender Slayer: Increases the damage dealt to ender dragons and endermen by 8% per level
Cubism: Increases the damage dealt to magma cubes, slimes and creepers by 8% per level
Critical: Increases Crit Damage by 10% per level

Snipe: Increases dealt damage by 0.1% for every 10 blocks traveled per level
Aiming: Arrows home towards nearby entities if they are within 2 blocks per level

All items (except armors) can have Telekinesis (block and mob drops go directly into your inventory).

The enchantments will be shown if the enchanted item has no lore or the lore contains a string with 11 spaces.

If the item has more than 5 enchantments the description of the enchantments will disappear

The Enchantment Table is a custom enchantment table which includes all custom enchantments named in Enchantment List. It can be used to add enchantments to axes, pickaxes, shovels, hoes, bows, books, armors and swords. If you place an item in the table you can choose between 3 options. The bottle on the left has the lowest enchantment levels but also doesn't cost that much. The bottle in the middle costs around 35 levels and is better than the one on the left. The bottle on the right costs the most but has the best enchantments.

If you have an enchanted book and want to combine it with an item or you want to combine two items you can use the anvil. The xp costs are based on how many anvil uses the items have and the levels of the enchantments you want to add.

You can change the lore except the lines with the stats. You can remove them but then you won't get extra stats. You can change the descritption of the abilities in every way and it'll still work. If you want to remove an ability just the the upgrade_per_level.abilityname to 0 or if you want to add to a pet set it to > 0. You can only add abilities to other pets if they are the same type

Pets can increase your stats and increase your damage by a lot. The stats you get depends on the level the pet has. You can level your pet by breaking blocks (configurable in config, all blocks can be added).
Every pet has one or more unique abilities (depends on rarity: common, uncommon, rare, epic, legendary).

There are two pets already added:
Ender Dragon and Tiger

You can add more by copying everything after tiger or enderdragon and paste it at another place. Rename it to the pets name (no spaces or "-"). Then you can set the texture, lore, abilities, stats etc..

You can change the lore of every item in the config.
