Vampiric Touch.
As long as it was an enemy with lifeforce, this spell would work. Its damage was quite stable.
At present, Soran has never failed in using it. It could reduce the life force of the opponent and restore his own injuries. Unfortunately, it could only be used once a day, and Soran could only use it when he was desperate. As for the "Vampiric Touch" from his own memory, since it was not a gifted type of spell-like ability, and there was no divine power as support, Soran had to use incantations to cast the spell and then be in close contact with the target before it could take effect. (Note: Casting time was about 1.5 seconds.)
In this case, it was not the divinity that affected the spell, but the spell's strength brought forth by his Wizardry level.
His injuries recovered at an alarming rate.
Soran caused hundreds of damage in a flash, but it was not fatal for the coarse skinned and fleshy Elder Earth Elemental.
