day time empress of light could be very challenging for new players or even veterans, even more so if you playing on master mode

you can check your best build/buffs from other places but the main thing I would tell is using shrimpy truffle mount during rain just making as much distance as you are comfortable with doing this will make most of her attacks obsolete also be careful of her dash when you see her dash to you try to 'go above and change direction' or 'go below and keep moving' also try to circle the ethereal lance attack I know shrimpy truffle can be annoying on vertical movement but it shouldn't be hard, also try to stay high and be ware of wyverns.


also if you can't beat duke I can make a guide for that as well I would mostly recommend inferno potion and also way of dodging the attacks.

thanks for reading and good luck with the fight.
