About healing surges

[username_]

Can someone please explain in what ways they can be used?

 

[Dalzig]

In combat: Second Wind, healing potions (for a fixed amount of HP), and various powers such as Healing Word.

Out of combat: Taking a short rest allows you to spend any number of healing surges.

Each time you 'spend' a healing surge, you regain HP equal to your healing surge value.

You can also expend them in other ways .. just a few examples:

To recharge Bloodcut Armor's power.
To maintain a longterm ritual such as Forbiddance.
As a penalty for failing a skill check, or any other plot narrative, as a replacement for "you take X damage" 'cos it's simply more convenient.
