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.
The ones that I have used, and can confirm work with Arc, are
Blood Magic
Faster Casting
Lightning Penetration
Reduced Mana Cost
List of support gems can be found here.
Any others may work, but I have not tested personally, therefore would be total speculation, on my part.
The first line in the description fo every gem contains some tags, i.e
In this example Glacial Hammer is Cold, Attack and Melee. That means that any support gems with any of those same tags will add its effect to it.

When you hover over a socketed Support Gem, it now shows what Skill Gems it affects by making them glow. The same is true for Skill Gems showing what Support Gems affect them. This currently does not properly handle the case of Support Gems that change a Skill Gem so that it enables or disables other Support Gems.
The support gems also have "tags" on them, which show what KIND of support gem they are. The support gems will work with all matching tags.
