Reflect Physical Damage: works on melee & ranged weapon hits, but only if they deal physical damage..
However it does not work on spells which deal physical damage or chaos damage at that.
Bombard, Earthquake do not reflect physical damage, & chaos damage (Spell plague, Nether bolt, nether cyclone & Word of Death) do not reflect with RPD.
RPD does work on Chaos damage weapons about 20% of the time this also includes the quiver of elements.
