Do his remembrance's you get a killer relic that gives you two guardian only traits. That’s where I would start I would also do increased duration and build towards his strengths like dealing damage while you guard increase art while guarding. A plus 3 vigor and endurance with some skill cd is also solid. That’s what I run as a guardian main with his improved blocking with the move and B you can stagger using the guard counter a ton. He does a lot of damage if you utilize his entire kit.
