Is it possible to improve the Lvl 50 lifetap spell Touch of Volatis since this is a dropped spell from the Scroll keeper in the Hole and other vendor purchased life taps are more efficient and/or tap for more life. They all share the same timers so its not like they can be sequenced while waiting for the other gem to pop.
Drain Spirit = 213 mana for 314 hp
Touch of Volatis = 291 mana for 216 hp
Life Leach = 181 mana for 175 hp
Life Draw = 86 mana for 90 hp
Thanks,
