With Darius LV4 Full Set, 10% bonus is +1 stat to ATK and DEF only.

With Terra LV4 (3 of 4 set, missing the Shield, with You already have the 10% hero equipment set bonus displayed), I don't get any 10% bonus at all, no display at General stats, and by manual comparison.

However, with Darius LV5, the bonus has increased to +2.

Therefore, the bonus comes from the RAW Hero's ATK and DEF (each, and independently): LV4 Darius (19/19), LV5 Darius (20/20). Apparently, there is no rounding off here.
