Question regarding spiritual conduit

[RaoulRamirez]

Does the added spiritual damage is for the remaining of the round or is it until the end of combat, meaning you can stack it by +1 at each upkeep?

Thanks!

By default all effects are until end of round (unless maintained). This would have to be renewed every round for the +1 Spiritual damage. The cost is there to offset the fact that this is a more potent bonus than Might (which just boosts physical damage)
