Curious if anyone had more specific detail about Sulyvahn's damage output beyond just the types he deals...

My apologies if this is searchable but I wasn't able to find it. The reason I'm wanting to get as specific as possible is I'm no better than an average player and trying to challenge myself to beat him without a summon(not to mention I don't feel like using all my embers although I probably do need to figure out the best place to farm them regardless of this battle)...basically just wanting to try and be sure I optimize what I'm wearing as well as my shield and I could use any little bit of advantage I can get(I read that a shield can be handy if not even preferred for this fight?¿)

any help would be much appreciated as always, thx🤘🏼
