For the mathematically challenged (me), is there a general, simple, easy-to-remember rule of thumb for when a monster's AC is high enough that you should not use GWM because the -5 to hit becomes too much of a handicap? i.e. Rule of Thumb: Don't use GWM against an opponent with an AC higher than 'X'? Or are there too many variables to make a general rule? If it matters, assume a strength-based generic mid level player with a +4 or +5 to hit.

    \$\begingroup\$ Reckless Attack is a barbarian ability that lets you get advantage on attacks in exchange for giving enemies advantage to attack you. There's no -5 involved at all. Were you thinking of the Great Weapon Master feat? (Also, by mid levels a +5 to hit is pretty pathetic, by that point you should probably be at +3 to +5 primary ability plus a +3 or +4 prof bonus...) \$\endgroup\$ Sep 21, 2023 at 12:12

    \$\begingroup\$ If this question is about GWM/SS, then this question on the mathematical soundness of the feature is a likely duplicate. \$\endgroup\$
