Most conquers I fight spam their unblockable shield rush followed by a light attack and loop that combo until I'm dead. I know I can dodge it initially but once I'm caught in said loop how can I counter? Can't seem to block the light attacks in time
You can dodge the Shieldbash following the Light Attack, however in my experience it only works 50% of the time. So yeah, good luck, they're a pain to deal with.
Dodge the shield rush and then block the light attacks, don't try to dodge the lights. They'll either run out of stamina or realize it's not working and go back to being a turtle
