SoS Price Question

[ZeusStarBurst]

Gotta Question
I was wondering the value of an SoS weapon I got
It’s a Lvl 16 SoS +3INT, with a 9 crit. Its also got like 6 immortal, and 1 lucky, and maybe a higher durability.
I havent messed with SoS very much in the past, but when I saw this for 1 million, I jumped on it.
Im curious to know if I got a good deal, and I plan to alc it up to a plus 1 or 2, so how much should I sell it for when im done using it?

EDIT i forgot to mention its a glaive.
