This RoA shadow is made to solve problems one can face in an end game. Some comments can be about previous build that was life based. This is an advanced build that may be costly. [Disclaimer: the equipment still uses life build's.]
(Not updated for 1.3.0) Iron Reflexes.
Cheap to build lvl 67 physical lightning arrow build for ranger/scion. Allows flexible spec-in/out of HP and resist nodes as well as smooth progression through game contents. Played as first char in Nemesis, encountered no difficulties throughout the game (normal-merciless and reflect mobs)
