Here's an interesting one that came up in my game the other day.
My big beastie unit with beast banner got withering'd, reducing their strength by 3.
Now, a Gor is base St 3. The beast banner "grants the bearer and his unit +1 strength".
Does the beast banner give the unit a constant upgrade of strength 4? or does it add the their current strength at the time of use?
As they were in combat with T3 bloodletters, it was significant as they were striking at either strength 1 or strength 2, meaning6s or 5s.
Both FAQs were useless in helping us work it out so we d6'd it.
