Actually, It’s 11 aoe atk ratio for six mobs. And as @hubertorito mentioned, there’s a lot of options.
IMO everyone should look for at least 7 aoe atk ratio (four medium mobs), 7 is good enough for most things already like farming on open fields for materials.
Since I don’t have any phadas/glads and I like to keep my sissels, this is what I usually use for aoe ratio:
5 aoe ratio for 3 mobs: Black Horn (+1)
7 aoe ratio for 4 mobs: BH (+1) + Vubbe Fighter Gloves (+2) or Solmiki Gloves (+1) + one aoe ratio hat if somehow I need more def/mdef (I paid 500k for one aoe ratio pudding back in the days, kek). 7 is good when you aren’t in a tryhard farming mod so you don’t need to login your squire and etc
9 aoe ratio for 5 mobs: BH (+1) + Squire Food (+3) + Solmiki Leather Gloves (+1). Good balance of atk (since I can keep 3 physical atk hats), aoe ratio and defense (vubbe’s def is shit)
11 aoe ratio for 6 mobs: BH (+1) Squire Food (+3) +1 aoe ratio hat (+1), Vubbe (+2). I’m going to craft a phada one day maybe… so I can keep the solmiki gloves while using the 11 aoe ratio setup lol
edit: special mention
6 aoe ratio (so you ca hit two bosses like in siauliau): BH + solmiki leather gloves
There’s also a alchemist potion that gives +3 aoe ratio for 90 seconds (60 seconds CD) and many other items like that new world boss accessory set, but they are expensive as ■■■■. Regardless, you’re locked in 4 aoe mobs only if you want to suffer
