I felt that there needed to be a range for the wizard to shoot for. With the fighter and the assassin there is a clear “target”. Get close to the monster, but don’t touch it.
The wizard it was trickier, since they were at range with no clear “marker” to shoot for. I played with a couple different distances to shoot for, and settled on giving the wizard a 1inch range band to fall within.
also just realized that 4.4 is a typo on my part. Should read 4.5…
