When used, the message "Your hands wither." appears. The next time an enemy is hit for a certain amount of damage, that same amount is regenerated in the user. This effect is also applied if an ember is used to hit the target. Any damage done with a drain effect will appear as gray text as opposed to red. When the effect is used or wears off, the message "Your hands feel normal again." is displayed.
A Magic Skill level of 12 is required to use it.
Interestingly enough, it is possible to get a drain with a Morning Star of Drain Life and this scroll in the same attack, causing two drain attacks in a single hit.
