But that isn't necessary. There's not, or at least shouldn't, be a enough of damage in any mechanic to one shot you or your entire party. The reason it's good on SCH is because with their crit heals they can add a significant % to your tanks health. Your shield doesn't really do that. Precasting a benefic 2 would put your tank at a much healthier range than a mediocre shield would. Perhaps it would be worth it if aspected benefic was ONLY shielding, but it's currently far too small of a shield.
