Does anyone know what level these two revered dragons are, also how much health they have and their breath attack damage and bite. I ask this because while killing these two on adept with 55% magic resistance they were very powerful. Their breath attack could take down my level 54s 300 health in no time. Also they seemed to have lots of health as I single casted expert fire destruction spells with all the damage perks, also a storm atronarch.
I would just like to know how strong they were, anyone else think they were powerful.

i can't really give you accurate numbers. When I fought them, they went down pretty quickly (at level 42). Then again, ripping off all three words to Marked for Death makes most things go down pretty quickly...

They were a fun fight. Not necessarily hard, but fun. Brought one down with Dragonrend, then worked on the other after the first was dead.

In retrospect, using all 3 words of Storm Call would have been at least 3x more epic.

These dragons are not necessarily Revered, they are leveled. I saw a youtube play through where one was revered and the other was ancient.

The Drain Vitality shout is very powerful. Even with 85% resist magic my health drops pretty far. If I get hit by it twice in quick succession I am definitely in need of healing.

As one poster above recommended, use Marked for Death, this weakens their armor rating and allows your own and your follower's ranged/melee weapons to do more damage. Marked for Death is especially good for dragon attacks on settlements since it allows the guards arrows to be more effective as well as your own.

this battle took me freakin 45 minutes... using twin souls dremora, duel dragonbone swords with a mix of marked for death and dragonrend AND serana limping in a corner and one dead thrall. I enjoyed it haha

I use all three words for slow time spell, then use lighting storm. It kills every single dragon regardless of their level in under a minute.

I dragonrend owned them the first time. Second and third times, werewolf. Another time as VL.

I had no problem with this fight. Was wearing vampire armor and my light armor skill was trash at that time, was wearing it to level skill and it looked cool. But wielded a dragonbone sword legendary. Serana dropped to fast to be any use. But I beat them both in two minutes maybe less. Only used dragonrend shout. No I didn't spam it to stagger them.

'Twas an epic battle as a vampire lord. They were quite hard, but it might have been easier if Serana wasn't on the floor the whole time...

On adept level neither of my first two characters really had an epic battle. But my second character at level 61 also tried the two higher difficulty levels in an attempt to get two Legendary dragons. She failed, but the fight on the highest difficulty level ended up with a Revered and what seemed to be an Ancient dragon and was certainly a lot more epic. The fight on the second highest difficulty level netted her two Revered dragons that were no harder than the ones on Adept level. Still I am a chicken who is going to stick to the Adept difficulty level.
