Great synergy between these Abyssus and Lightning Coil.
One increases physical damage received, while the other converts that damage into lightning damage, which can then be mitigated by resistance. Here are the mechanics between the 2 uniques:
The physical damage received, after armour, from the worse possible rolled abyssus (+50%) totals 150%. The lightning coil converts that into
90% physical
60% lightning
Our lightning resistance is at 75%, which then becomes
90% physical
15% lightning
105% total damage. Only 5% more damage than otherwise.
The major difficulty of this set is maxing resistances. The 60% lightning resistance required plus the chaos resist to run blood rage will prove to be very tricky and expensive to juggle.
