Support gem - Cast On Hit

I love this idea:

And its actually 2 gems... on hit(should be limited to attacks imo) and on being hit

I would change the qual to 1% on crit/being crit. Also I would decrease the base chance to 10% and add a 50-70% base damage modifier.

Problem with this skill is that it would cost no Mana... maybe it should reserve some (150-200% skill cost maybe?).


I would love to try: On being hit+ice nova+increased crit chance

Edit: bump
