Is it possible to increase the healing from Shaman's Life Link Hex? At higher levels, 5 hitpoints per round are not such a big deal. Also because it can heal one person once per round it is way less viable against multiple attacks directed at a single character.
I know of two ways to increase the healing provided by Life Link. You may be able to find more abilities that work similarly.
- Lesser Celestial Totem - Any creature affected by this rage power will receive additional healing equal to your class level whenever Life Link triggers. You can take 3 levels of Skald and choose this as your rage power. This will allow you to give the rage power to anyone who accepts your Inspire Rage.
- Hierophant Spirit - With a single level dip in the Medium class you can receive the benefits of the Hierophant spirit, which will increase your Life Link healing from 5 to 7.
Note: With either of these in effect, you would still only lose 5, regardless of how much you heal.
