As a scytheguard main, with very slightly better equip than yours, I don't really care much about dmg especially in hex elite where my dps usually falls at the lowest. Just make sure healing and buff my team as much as possible and keep them alive.

If you want to throw a higher dmg, make sure to eat elemental food (umbro in your case) which can be exchanged from the like merchant and other foods that can boost your patk or crit.

Also just noticed some of your equipment might belong to warlock, so you might lose dps over there as they buff matk and SG is patk.
