The spell affects up to one target per 2 ranks within a 10 (+2 per rank) diameter area. The spell cannot affect targets who do not need to sleep, or targets with more than (rank x 5) hit points. This refers to the target's unwounded hit points. Thus, if an unwounded target has 50 hit points but is currently down 40 hit points due to wounds, they cannot be targeted unless the mage is rank 10 or higher with this spell.
If the target is within 10 hit points of the mage's max, then they can be awakened if shook, etc. Otherwise they cannot be awakened until duration of the spell is expired, a counterspell is successfully used, or other magic that awakens sleepers is used.
For example, if the mage is rank 10 with this spell and targets 5 orcs with hit points of 42, 40, 38, 32 and 28. Being rank 10, the mage can affect up to 5 targets with 50 or less hit points. Each orc is allowed a magic save to resist the spell. Even if all of them fail the save, the 42 hit point orc can be awakened if shook as he is within 10 points of the mage's 50 hit point max (the 40 hit point is just barely out of the range - he would need 41 hit points to be awakened by shaking). |
