maybe i'm wrong but i think the str bonus u get from the set is ADDITIONAL to the str u get from each piece (12 at +7 just like shells)You honestly need a full +7 set. When you have one the +15 STR bonus gives +3 STR to each piece so you have the same STR bonus as a +8 Set. Plus you get more Hp, mana, and res. Mixing ain't good unless the pieces are all +8.[/b]
please correct me if i'm wrong
edit: i misunderstood sorry h34r: my post is useless.
