I have a lvl 40 elin with random stats that needs control can you please help with stats

Current stats
Str 3
Con 21
Int 12
Wis 5
Agi 30

What needs changing?

You could get rid of the int and agi, and add it to str and con.

You could get rid of that too. Since rb gives u wis.

Wait i must get rid of wis now but rb is probably 100 lvls away so should i keep it for until i rb ?

well ur elin is level 40 so it's 60 levels away.
It's better to scroll your pet now before rb so it could add on the right stats.

I personally would go for the highest CON possible. Adding to STR mostly affects her chaotic attack move. She cannot be HF so adding to STR feels like a waste imo, but it depends on what you want her role to be for your team.
