Never done this crap but like to give tips if u want ! Did it in one try First we were 291 293 and 288 u will need good weapons and the sword at least 280+ its a true weapon for the adds and even boss. We just ran through the beginning got to the ogre killed it and booked it back didnt fight any adds one guy grabbed the relic from top another grabbed at bottoms after the first door. It takes just one guadian to get to the door once u get to the room where u get three all relics or perhaps kt was the extra one just ignore it and look for the entrance to taniks strike if ur lucky and quick the door will be open u will know if it triggered bc u will get a strange transmission go up the ketchup and fight through the taken u got ten mins so be quick dont die u can but there a half ass wait time to be revived so kill quick amd go to the boss room once u get there u will see tons of adds and Taniks the taken lol waste no time with adds spam grenades and sword the shit out of the boss if u dont I've heard the adds will continue so take out the boss then quickly deal with the adds there alot alot of super usage will be great if u have supercell u can get the bolt lighting chains going but if u need anything else let me know!
