Im the same here, i need help for this as well so i,l team up with you if you want. Youl need solar weapons. A special and a heavy weapon with solar. The solar weapons are needed for the wizards. Also you want weapons with arc damage for the blue Knights. These points are important as these enemy's are taken easier with the right damage type for each. I tried it without these solar and arc weapons and we got wasted. It takes far too long to kill these without the solar damage and you just get swamped. also remember the big boss at the end needs to live so you just ignore him and take all the waves of enemys around him till XYOR appears, then you can finish him off. Will definate help to stock up on special amo and heavy weapon amo from the gunsmith before going in. I know they have 5 minute timer to use each time but theres no rush anyway and always stock you up again. Im on PS4 as well user MysticXS i,l add you and say Thorn bounty so you know its me. -- cheers
