Instant Leech from Claw Mastery doesn't properly instant leech Energy Shield and Mana

The 20% Instant Leech from Claw Mastery only actually instant leeches Life, even though there is no indication in the tooltip of that.

Meanwhile Leech Mastery has identical tooltip wording but DOES instant leech Life, Energy Shield and Mana.


Claw Mastery:
10% of Leech is Instant per Equipped Claw

Leech Mastery:
10% of Leech is Instant
