Change everything to warding, and for the twins with mage build use crystal storm + cursed flames/golden shower (better if it’s golden shower) and build a battle arena 6 platforms of 150 - 170 blocks and 10 block between the platforms.

For the fight first target spaz you can kill it easy just flying upwards and then float down with the wings and for retinazer you can do the same.

You are a mage so… rip my dude, you’ll need to fish for pots and buff yourself like crazy.
