As a melee shield user on hardcore I like to play with the auto-defend skills. Reckoning, Riposte and Vengeance. However when it comes to support gems it seems some of them don't work. I've tried Life on Hit, since the point of these skills is to act defensively.
Is there an overview of what support gems work with what skills?
I find this to be a problem in general, some times it's mentioned in the support gem, but even then it can be unclear which gems are meant specifically.
