Sentient Sword

The Sentient Sword is a weapon added by Blood Magic for Minecraft 1.8.9 and above. It and is used to collect Raw Will. This Raw Will is automatically added to the top left most Raw Will Tartaric Gem in the player's inventory. If all available Raw Will Gems are full, mobs will drop Demonic Will. It is capable of being enchanted. It can also be repaired by using a Demon Will Crystal in the Anvil.

Statistics
Its attributes change depending on Will amount and type stored in all Tartaric Gems in a player's inventory with the highest amount of one type taking precedence. If the highest will amount is tied, the priority is (in descending order): Default, Steadfast, Vengeful, Destructive, Corrosive. The Sentient Sword upon crafting it deals points of damage and has 1.6 attack speed, changing to at least  points of damage after first use. The properties are based on tiers of will, which also increase Raw Will drop on kill and drain per swing.

Will required for each Tier

At tier 5, dropping the sword on the ground will consume 100 will and spawn a Sentient Specter. This specter is an animated version of the Sentient Sword and it will follow you around. It can be picked up by shift right clicking or killing it. If wounded, it will spend some time to heal outside of battle. The specter will attack anything you fight - whether you attack or are attacked - except for creepers. Note this also applies to players. Enchantments are retained through this method, and the sword will not lose durability in battle this way.

The remaining temporary hearts will persist until damaged, but will still only stack to 5 temporary hearts with additional triggers.
