Maybe this can help.
Just make a team accordingly, and you're good to go, I guess.
Only Solo. If you're good that's one or two servants per break bar.
Last battle with ORT you'll have your servants back and NPC buffs so just go with Alter Ego+stuff to counter the Foreigner class diasadv.
If you dont have the servants to challenge ORT then dont bother, ORT is not made to be fought by beginners.
What do you think?
