It's complicated and I'm going my memory,but I'll try my best.
Basically,Odin,Vili,& Ve travel to Surtur's land of Muspelheim.It's quoted that they had slain Ymir(who is certainly well above a standard class 100.) Then,it's quoted that they are the Sons of Bur,Grandsons of Buri.And,first of the immortal style Gods.One of the Brothers already demonstrates storm powers.All this,keep in mind,is before Odin gets his Brothers physicality or power.
They combined powers and engage Surtur.After a battle,Surtur's sword is broken and the brothers parted.One brother slashes Surtur's flame mount and Odin casually catches it.Then Odin,in one arm,rides off still holding the Eternal Flame inside the torch head(keep in mind this thing is seemingly larger than Odin himself.) Vili & Ve follow.Upon approaching the exit to Surtur's realm,Odin keeps riding with the flame & torch container still on him.But Vili & Ve stop.Odin looks back and the exit from the realm is gone.A moment later,Odin is now what all three brothers were prior to such.
I just never got the sense that each brother was around a class 10 there before passing on thier abilites to Odin.Nor did I see any reason to feel Odin didn't get their physicality but got everything else.And honestly,given their heritage,I didn't see a reason to think they weren't superior to normal Asgardian farmers and the like,anyway.
