The Greatbow and Compound Greatbow require 18 strength to draw, meaning they have an optimum strength of 36. AFAIK, unaugmented human maximum is supposed to be 14. It’s therefore useless to all but hulked-out mutants who started out as world champion powerlifters… and can only brought to a full draw with Hydraulic Muscles active.
Which is cool if it’s intended… but seems like it should be reflected in the item description. “Requires incredible strength to draw” implies something like min 9, optimum 18, to me. Which makes me wonder if this was an accident.
