Unless I'm trying to stack a particular resistance for a particular fight, or want to dabble with heavier weapons for a bit of fun, I almost always fall back to Gundyr's set. Has solid absorption, poise and resistance with the only downside being weight (shock-horror). Looks good and only has a few blemishes.
Yes, I'm one of those people who played DS3 blind a few years ago and ended up with full Gundyr Armor + Gundyr Halberd. I said I'd do it differently all these years later, but it's hard to let this well rounded set go. Just ironic how it stems from (technically) the first boss of the game. Yes, I know, it's primarily from ChampGun, not RegularGun, but you know what I mean.
