So I just got through a pretty long string of bosses (at least for me) in a single life. For a while, I was getting my ass handed to me before something clicked. I got through The Last Giant, The Pursuer, Dragonrider, and Old Dragonslayer (in that order) all on a single life with humanity restored. I can't say I've had this level of video game induced high in quite some time.
What is your highest streak of bosses defeated on a single life for Dark Souls 2? Doesn't matter if you cheesed them or called in some help, its all part of the game and it all counts.

Uh, one. Do I lose my cred?

I've beaten three(?) bosses in a single try so far, but I don't think I've ever done multiple bosses without dying at all in between.

I can't even imagine beating The Pursuer on my first try, even with summons. I've had my summons shoot me in the face so many times... (granted sometimes it's my fault for getting in the way). I've done two in one life so far: The Pursuer (after 7 tries, when my summons finally clued in that I just wanted to gank this fool, old school) and Old Dragonslayer.

@cloudymusic: No way, man! Death is part of the experience, EMBRACE IT!

@skyrider: I got really lucky with the ballista and was able to take him down to where one hit would kill him. He's definitely my favorite boss design so far but damn is he hard to hit.

Fallen Giant, Dragonrider, Old Dragonslayer, and the Gargoyles all down in one. All the other bosses...well, let's not talk about that right now.

@tolman - I had much better luck with Pursuer by ignoring the ballistae and just focusing on dodging back and to the right and getting one or two hits in while he was busy twirling around and grandstanding. I must have died at least 10 times to him when trying to use those damn machines. Ironically, the first time I decided to ignore the ballistae, he quickly destroyed them both anyway.

I have no idea, maybe three. But if we are including helping others kill bosses. Probably in the high 40s. That is all I did today. I have so many of those giant white stones. Which is good, because that covenant needs so many to level up! 500 of them for the third level! WHAT!

I did 3 bosses, The Last Giant, The Dragonrider, and the Flexile Sentry.

Everything else has taken 2+ tries. I don't want to talk about Ruin Sentries or the Lost Sinner.

Old Dragon Slayer, the guy in the pirate ship, and Ruin Sentinel all in one life.

last giant, the pursuer, old dragon slayer, flexible sentry, ruin sentinel, belfry gargoyles

this includes the areas in between =o

(but not helping others in co-op or invading other players)

I got through 2: Dragon Rider and Dragon Slayer.

How the hell did you guys get through the Gargoyles in one shot? Shit is totally unfair. Maybe I should be summoning duders?

0.5 bosses in one life.

Actually those exact guys you mentioned. And I think the flexile sentry / gargoyles? I think? I got pretty overpowered early on, though the game's difficulty curve's starting to catch up

@weegieanawrench: I'm to the point of summoning. Every time I try though I get invaded by Grey phantoms.

I was able to take down Old Dragonslayer and Dragonrider on the first try. Though that was after spending an hour+ on the Pursuer, which forced me to get a much better handle on everything and gave me that great armor set and shield, plus some time exploring the area after the Pursuer giving me a ton of levels, so I pretty much rolled through the Tower area after that.

All of them. I'm the greatest.

I beat the Old Giant and the Persuer in one life. Felt pretty good, and now keep dying over and over an those three lanky guys (don't remember their names).

summon distractions =o

I tried. So far every single one has died either in one hit or lured the first guy of the platform, thus pretty much fucking up the whole run.

Nice thing with DSII is it rewards you for being competent, if you don't die then you're in great shape; if you die several times then you're in awful shape until you find the ring of binding (I didn't have it for half the game, pretty much got used to almost never taking damage as a route to success, turns out that's a good approach).

@sessh: The NPC summon there is one of the best in the game, check the cells.

beat every boss (Last Giant - that thing on the ship, about 6-7 bosses) without dying and then I got to the fucking Medusa (before I figure out how to beat her). fuck that boss.

Last Giant and Pursuer were the only ones for me.

I had a couple good runs--maybe 5 bosses in a row on the best one? I definitely felt like the overall boss difficulty was lower (or maybe I've just played enough of these to cope well with the new challenges), but it spiked pretty hard on a few fights.

Two. I don't imagine ever beating that record since I have a job and can't play Dark Souls 2 for 8 hours a day no matter how much I want to. I beat both the bosses in the Heides Tower of Flame area in a single run. The guy below was simple to roll and stab. The guy up top I summoned a helper to act as a diversion. Every time he went after my summon I kept stabbing him in the back. Easy peesy.

If anyone's curious, the trick to killing the pursuer with the ballista is that you need to put him close in front of the ballista (10 feet or so) - and then after he commits and does a heavy strike, dodge and sprint towards the ballista. Your timing has to be fast, because he'll only stay within the target zone for a couple of seconds as he recovers from the heavy strike. Did this and then I killed him in one hit afterwards.

Some how I managed four: Pursuer, guy(s) on the ship, Dragonrider, and the other guy (with summon).

It's not Dark Souls II, but I finished Demon's Souls on a super high note killing the last 5 bosses in the game without dying. Needless to say I was super pumped.

I got Dragonrider, Flexile Sentry and The Rotten on my first tries, no streaks, though.
