I have 175 PRR and only 84 MRR on my Bladeforged.
I have the Adamantium body feat.
I have the Shadowscale docent with Shadow Guardian
Removing the docent does not effect either my PRR or MRR
Equiping other docents does not effect MRR/PRR
Removing my Tower Shield does lower PRR (by lots) and MRR by 15
Communion of Warding (Bladeforged Racial Enhancement) gives 4/8/12 PRR should give MRR as well maybe?
Unyielding Sentinel Legendary Shield Mastery gives 5/10/15 PRR no MRR
Divine Crusader Heavenly Presence gives 10 PRR no MRR
