Alduin's bane - hit a bump

[grimstride]

I am doing my first ever playthrough and i have a bit of an issue. Im doing the "alduins bane" quest and i got to the part where i have to defeat Alduin using the dragonrend shout i just learned.

 

I make him go down start hitting him and im doing almost no damage (no its not the invulnerability bug) . I use dragon rend as soon as he tries to fly off >> hit >>> and repeat . After doing it about 4 times in a row i managed to get him to about 65% and my steam finally ran out .About 60% of my health disappears with a single breath attack with me blocking(resistance perk included) , im using resist pots , magic reduc ring and necklase + the lord stone . I have about 350 hp and lets say 80%+ fire resistance(hell with everything adding up it should be maxed out) .I heal up but my mana disappers quickly and i spam pots. I have about 500 armor and his wing and tail attacks still destroy about 30-40% of my hp. Im using poisons , hp pots , dmg increase pots , stamina pots , i try to stay away from his head but nothing works .

 

I watched a video where a person ended the fight in 1 min but after 3 min of non stop whaling at him i can barely get him to 70%.

Im level 34 a warrior character, playing at expert difficulty , 1hand 95 , heavy armor 87 , block is around 70 . Guess it took me a while to get to the main quest. I've never had any issues with the difficulty so far. I'm using orcish level gear + skyforge steal sword all epic. I tried dual wielding and enchanted my weapons which i was saving for later on in the game but i die too quickly. I've done other quests and explored a lot and i didnt really find any epic end game items so i assumed that would happen as i go through the main quest.

 

Any suggestions ?

Don't keep him pinned to the ground all the time. Give yourself time to heal up between two dragon rend shouts.

Maybe turn down difficulty.

In addition to what notmyhome suggested, I would add getting better armor and weapons. I got my smithing and enchanting skills up to 90 each so that I could fashion ebony armor and enchant it with various combat buffs. I already had an ebony bow that I'd picked up in a dungeon after a boss fight and I enchanted a Blades' sword with a nasty "steal health" enchantment so that every time I hit an enemy, I transferred some of the damage I did to them as extra health for me.

 

In summary:

 

Better armor: Ebony or Dragon (If you get your smithing skill high enough to make them as opposed to trying to find them in dungeons, so much the better.)

Better weapons: Again, Ebony or Dragon.

Enchantments: Armor pieces should have heavy armor buffs. Weapons should have one-handed buff (sword), archery buff (bow).

 

If you're determined enough, you can get your enchanting skill up to 100 and put TWO enchantments on each piece of armor and each weapon. You can really drive up your armor rating and damage output then.
