Bulwark of Ages, with the huge defensive boost of 25% global damage reduction you will have to heal yourself much less often  allowing you to keep more allies alive and you will be a complete pain to finish off.

you should get catapults and end the game

if you get alot of cheap items and fill your slots it's better than just 1 artifact plus cheaper

I wrote the guide to duelist sedna, so my playstyle is different. 

That said, I usually buy 1 or 2 items at the start and then 3 crowns from the regular shop. Then I save up for the 16k gold it takes to upgrade the citadel from nothing to giants, and this usually wins the game. Even catapultasauri can do it for 10k if you are low on cash.

If you are considering buying something from the artifact shop, it should usually win you the game. Most of the items in there won't.

Ashkandor is amazing and the most cost effective choice even at 18k. It will win the game against some opponents.

 

Ah, well, the reason I was wondering was I just played an UB where all I did was buy citadel upgrades, and I got smoked.

It was me vs. him (plus 4 AIs on each team) and I dumped everything I had into the citadel. He got items and an artifact, and proceeded to farm the AIs. There was little I could do to stop him from killing the AIs, as he was just as fast as me (if not faster) and I was busy guarding flags or healing the other AIs.

By the time we were in the end game, he had gotten a lot more gold than me, and even though he had more junk from citadel upgrades to push through, he ended up winning the game by dumping all the gold he had gotten from kills into superior upgrades in his citadel. I proceeded to lose the game after being overwhelmed on all sides.

It's situations like that where I think it would be good to get an artifact. Sedna just isn't really all that great at farming DGs when you compare her to a properly specced and itemed UB.

As a matter of fact, I've played a couple games that were similar to the above scenario, with the unclean beast ultimately getting really good items and becoming unstoppable late game. Most of the time when this happens I lose, because I have no idea how to counter it.

Thanks for all the replies!

I see a lot of people saying that sedna can't do damage, and she can't farm demigods.

I will agree that she is weak against minions and creep waves, but she is probably the best 1v1 class if you build her right. Especially against UB she can completely nullify spit. Pounce is one of the highest damage instant cast spells in the game as well.

Sonolegolas: he was playing sedna "against" an UB.

The problem was THAT. An Unclean Beast that is allowed to get kills and gold will spell doom for you. An artifact wouldn't have really helped you, since he'd get Mage Slayer and Ashkandor, hitting at 0.5X for 400-500's plus crits and drain. You probably should have gone for a DG killer instead of the support ones. It can be done, but I think it's unfair advantage, since he can get those AI kills faster than you can.

I had a similar game against a Torchbearer.  I was able to mostly defend my AIs from him and keep up with him on kills -- I was actually ahead for most of the game as I recall -- and my better staying power meant we had better control of flags.  I hit War Rank 10 while he was still around 6 or 7 and I was starting to accumulate artifact levels of gold, and so I did what I do when playing with humans: I sold some gear (Godplate) and bought giants.  We controlled both neutral portals, and I figured that giants would end the game pretty fast.  Big mistake.  I don't understand how he did it, but somehow he stopped my giants for long enough to buy his own giants, then started pushing my entire team back.  Before long I had giants coming from all directions and there was nothing I could do about it.

I say that it mattered that I wasn't playing with humans, because with humans I could have launched a concerted attack on one of his portals and locked it down while he was dealing with my giants.  Instead, my AI wandered around aimlessly and let him and his AI allies score endless kills, while I got killed trying -- and nearly succeeding -- to ninja his portal on my own (the Beast AI walked up and Foul Grasped me when I was 75% of the way through casting the lock!  Why couldn't it have used Spit instead?  Why are my AI allies never that smart?  ).

He didn't have that many more kills than me, and most of them came at the end when things were getting tough for us, but I'm pretty sure he was carrying at least one if not two or three artifacts, and it made it impossible for me to go anywhere near him.  I think that when I got to 8,000 gold I should have just kept exploiting his AI for money, either to buy giants without selling anything, or to get some decent artifacts (Bulwark, maybe) to keep up with his attack power.

How would you kill that Sedna when she stacks HP regen and life leech % in end game?
