Several Things

-Now, every tools/armors created with a material with a quality at least equal to ruby will have an effect directly. This effect increases in term of power when you upgrade to the ultra version.

-Changed the way ultra wooden tools work : the ultra sword/axe inflict extra damage based on your health /2.

-Changed the way ultra stone tools work : the ultra sword/axe inflict extra damage based on your experience level /3.

-Changed the way ultra iron tools work : each time you kill a mob with an ultra iron axe/sword, you and players nearby gain a little experience. Each time you break ores with pickaxes, the same thing happen.

-Changed the way ultra iron armors work : each time you pick up experience orbs, you and players nearby gain experience.

-Changed the way golden tools work : each time you hit an entity with the axe/sword, you have one chance in thirty chance to regenerate the tool based on your experience level and to spawn an experience orb with an amount of experience calculated in fonction of the durability of your tool /10. It's the same thing with the pickaxe/shovel, except it happens when you break a block.

-Changed the way the ultra diamond tools work : each time you kill an entity with the sword/axe, you gain 1/5 of the experience needed to pass the next level. The ultra diamond pickaxe now functions completly differently : you can right click with it on a block (ores and stone/deepslate) to "upgrade" it, at the cost of levels and item durability.

-Changed the way the ultra diamond armor works. Now, health boost will be reset every 24000 ticks, with no hearts loss. ( They'll have to be regenerated, though.)

-Changed the way the ultra emerald tools work : if your level is superior to the entity's max health you attack, in exchange of one level, the entity targeted will take the amount of levels you have as damage. The pickaxe now gives you experience points multiply by the harvest level of the block mined, with a coefficient 2.

-Changed the way the ruby tools work: pickaxes, shovels and axes will regenerate your armor and your item in left hand each time you break a block with them. Axes and swords will regenerate you each time you kill a mob with them.

-Changed the way ruby armors work : when you're about to die, if you're at least level 10/20/30 (depending on the piece of armor), in exchange of all your levels, your death is cancelled.

-Changed the way sapphire tools work : each time you kill an entity with the sword/axe, you regenerate the durability of your armor and item in left hand. The sapphire pickaxe has a little chance to make ores spawn each time you break a block with it.

-Changed the way sapphire armors work : when a mob hits you, it takes damage regarding of your current health.

-Changed the way the amethyst tools work : The amethyst pickaxe will mine 3x3. Same for the amethyst axes and shovels. The amethyst swords/axes now inflict damage to mob in a certain radius when you kill one.

-Changed the way the amethyst armors work : In a certain radius, almost all creatures will have their health halved by 1.3/1.6/2 (depending on the piece of armor). In return, each day, the wearer will lost levels of experience depending of his health. If the wearer has less than 10 levels, the armor will begin to suffer damage. Below ultra version, it affects only creatures with 20 health points or below. With the ultra version, creatures that have between 20 and 40 health points are also affected.

-Changed the way the crystal armors work : when a mob hits you, it takes damage equal to your experience level divided per 3/2.5/2, depending on the armor piece. In return, you lose experience proportional to the damage inflicted. When you're under the level 10, the damage inflicted to you are multiplied and directly inflicted to the armor.

-Changed harvest level of the ultra amethyst pickaxe to 7. (Was 6)

-The levels cost of the Repairer is again 3 levels.

-Ores of Several Things now drop orbs with experience instead of just dropping empty orbs and giving experience directly to the player.

-Complexified crafts regarding medkits.

-Deleted all advancements.

-Added amethyst ore blocks. They are not spawning naturally.
