hero can only use 2handed weapons after Big Bang?

level 20 shields can add max 3% str

per slot

a 20 att ms shield will need about 5-6 percent str. 16 att needs about 9.
its not unattainable. however, higher shields may offer up to 27 or 36 percent str and will be preferable, especially because more of the bonus is in str instead of w att (for applez). but you only need to tack on about 18 percent to your range if your 1h and 2h are the same speed and att. about 10 if 1h is faster, which is easily gained from just w att on the ms shield.

kiwi, multiplier for 1h is 1.1, 2h is 1.29.
