.Pyromancy makes the fight with O&S much easier. Get it to +15 and 2 atunement slots (I don't know what your stats are)
Always keep both in your field of view, target Orstein (the slim one) with fireballs. It might sometimes hit both. Once you take 1 out, the rest of the fight becomes just a regular Souls boss fight.
Can you post your stat screen?
I don't think I can use it to with my build but thanks for tip!
i did all melee. used the pillars to keep them separated, killed the big guy first. he hits hard but plenty of time to get out of the way. took my time, wasn't ashamed to run and get behind a pillar, don't get caught out in the open
after the first one dies, the second one heals completely so don't bother hitting both
did lightning spear guy second. stayed underfoot, between his legs and behind. watched for the jump up which is nasty aoe. roll away, come back when it's over. being in front of him is terrible, no-man's land
these tips were helpful thanksI found it easiest to concentrate on killing Ornstein (the small one) because he likes to come to you. Basically I just jogged backwards in a circle around the room waiting for opportunities, jumped in with some quick slashes against Ornstein when I saw a chance and then rolling out of the way of Smough's hammer that was inevitably going to smash down from off-screen after a second or two.
Phase 2 Smough ain't shit, so if you get that far you've basically done it (do still be careful, though, because he hits hard).
I am trying to beat the game using Zero summonsPretty sure you can summon Solaire in the hall outside S+O and he's a huge help distracting one while you take the other out.
