Right now my weapon has immortal 4 times on it (came like that) do i need 4 astrals or can i just buy as i need?
why does the price go up for each level of astral? say i wanted 4 astral, would i need to buy astral lvl 1, 2, 3, and 4 or just 4? or is it like lucky power and i buy it to match the degree of my weapon, in which case i would buy 4 lvl 4 astrals.... aaaaaaaaaaaaah!!! help???
reason im asking is i had +2 originaly, went for +3 and it failed

Since then i added a crit stone which took me from crit 4 to crit 14

so i def dont want to screw this weapon up again, but at the same time i want to make it the best it can be.
