It depend on class probably, i am thinking a LK vs champ duel. Look interesting with the shiled preventing knock back.
Actually that will allow LK to spam BB/Bran and the Champ will take 20% more dmg .
The tactic remains the same - Pneuma- Relocate out and heal and attack.
This shield would have been great if warps were still there in PVP to check Warp wh0res.
