What resistances are actually needed to survive against Morgoth?

I'm using a ranger so I plan to barrage him with arrows. Does he have resistances of his own?

Also have big stacks of Rods of Teleport Other and Rods of Slow Monster

Don't forget he summons a lot. Bring as many resistances as you can in case you get in LOS of some nasty summons before you can discard them.
