Soul Based Enchantments

3 new enchantments based on souls: Spirit Flame for the bow, Soul Aspect for the sword, and Soul Drain for armor. Spirit Flame and Soul Aspect are pretty self-explanatory. You strike a mob with enchants and it sets them ablaze in soul fire. These enchants would interfere with Flame and Fire Aspect. However, Soul Drain would work a lot like thorns, where the attacker is hurt back when attacking a person with the enchantment. However, unlike Thorns, the damage will be dealt over time, from 3-5 seconds. The attacker will receive 1/2 of the damage dealt to the wearer and the wearer will heal 1/4 of the damage dealt. Leftover health can be turned into saturation. However, if the wearer attacks the attacker while the effect is active, the effect on the attacker would be stopped and the wearer will have their life reduced back to what they would have taken. The enchantment would be completely disabled against an attacker who is wearing Soul Drain or is using a soul fire inflicting weapon, to make PvP a bit more fair. The wearer does get reduced dmg to soul fire, however, taking the same dmg from soul fire as regular fire. The effect wouldnt put the attacker in soul fire, but would instead have the same particles that come out of soul sand when walked on with soul speed on top of the attacker's head.These Enchantments would be found in structures like bastions or a new, harder structure and not in an enchantment table/fishing, as it would make the regular flame enchants useless.
