help me beginner fighter

[fukdeathnote]

when people say str:end 2:1
does it mean that my bracketed str must be 2 times of my bracketed end
or.. my original str must be 2 times of my original end? (the one not in brackets)

and when is it recommended to start adding spr?

All the guides refer to the (+number) not the total.

Not sure when to raise what stat. For me it seems it's best to start with END only (the additional HP and Def are really useful at the first 20 levels), then raise SPR up to 25 at some point (if you want crits in your build), then either raise END or STR again (depending on build).
