Sleep and other distractions during 'Dominate Person'

[Pelthain]

Basically, if the caster of 'dominate person' is distracted, do they make a concentration check to keep the person under their control? It would seem a bit pointless if the spell lasted 10 days but a bit of bad weather would break the link.

However, the other alternative also doesn't make sense- in the middle of a battle where dominate person has just been cast, if the caster takes damage surely it would break her concentration?

So basically, it's either overpowered, or underpowered. Which is it?

Hey there Pelthain - you probably want to delete your other duplicate post ... :)

The spell doesn't require constant concentration. The subject continues to obey the last command given, even if you're asleep. Casting the spell can be interrupted, but that only lasts for a standard action.
