This Symbol will grant the Paladin the ability to Power Word Directed Arcane Rebuke Undead and Demons. To use this power the Paladin must state in a loud voice “In the name of I rebuke you, Undead/Demon! Power Word Directed Arcane Rebuke Undead/Demon”. The target is physically pushed 36 away from the Paladin until it is at least 10 feet away. The target may not get closer than 10 feet away from the Paladin while the Paladin maintains concentration and holds their Holy Symbol towards the target at eye level with both hands. If the target cannot retreat any further and the Paladin approaches the creature within the ten feet, the effect will fail. This ability can be used at will but it takes 1 minute of prayer to recharge for further use. This will not function against vampires and some unique or powerful Undead and demons. If the target calls “No Effect”, the ability cannot be used until the next reset.

So, looking specifically at the "it takes 1 minute of prayer to recharge for further use" section. Can you fight and pray at the same time? Or is it a concentration style thing where you have to run off and find a quiet corner. I thought that as long as you were giving your prayer it didn't matter what you did at the same time, as the skill doesn't specify, but others disagree. 

Thanks!
