Lay of Hands questionFollow

I am totally oblivious to what Lay of Hands do...

could someone please explain it to me?
sorry for the noob q.

Thanks in advice

It's a backup emergency button. If you're absolutely out of mana and need to live, use Lay on Hands on yourself or a party member (using it on yourself might be better since you can always ressurect someone later) will restore either yourself to full damage or someone else's HP equivilent to your maximum HP. Basically if you have 600 HP it cures for 600HP. Lay on hands has a 1 hour cooldown so is basically only for duels/emergencies.

The best part about it is that it works at full strength even if you have very little mana. Using 10 mana to heal someone for your maximum mana number is an awesome emergency button. Just be prepared to use a mana potion.
