>>21008385he's wearing heavy armor and fatrolling, but only has 31 vigor which means really low hp. He's also using radagon's soreseal which significantly reduces your armor. So it's just a big waste of stats, he isn't investing in the stats he needs to actually be tanky, but he's still wearing heavy armor and trying to play tanky despite wearing a talisman which makes his armor weaker
he's also carrying two swords and two shields at once, which is really inefficient. You're much better off carrying the alternate equipment in your inventory instead of wearing it around all the time, which makes him even heavier
his talisman choice is bad, again the soreseal gives him extra stats but it's absolutely not worth it at his level due to how much it reduces defenses. The turtle talisman is ok but just not very impactful, and then otherwise he's using weak versions of other talismans which have much better versions available in the late game
For his stats, the biggest problems are his vigor, mind, and endurance. The vigor is ridiculously low, he should have at least 50. The endurance is also really low. For some builds 23 end is fine, but wearing heavy armor you need much more. The mind stat is way too high, it's much better to allocate those levels elsewhere and simply rely on mana potions to refill instead.
He's also wearing radahn's armor, which isn't necessarily bad but is the stereotype of a casual noob, or a "kevin". Kevin always wears radahn's armor.
And then based on the fact that he has three different spirit summons on his bar, it looks like he basically just summons for every fight and then casts spells while the summons take all the aggro. In other words, he doesn't know how to build his character, he doesn't pay attention to what his talismans do, he carries way too much stuff at once and slows himself down because of it, and he cheeses every boss by summoning so that he can run away and cast spells. He's the epitome of a flavor of the week casual.
