Sort of impossible to just look at numbers and get a feel for it. Min and Max damage range is huge on weapons. You can hit incredibly low with a long spear you would swear the short spear has a higher max damage chance. Damage does seem to be capped at 110, and I have hit very close to that with war hammer crushing blows. Halberd can certainly reach it with swords/anat/tact. Only way to know is by passive melee gains and I guess faith. I remember chopping trees with halberds in the launch of trammel on OSI. I'm certain of this, and I remember being told to ditch my halberd for axes to kill lichs as I was wasting my skill. I didn't start UO til trammel launch, so not sure if that was the change or a creation of a bug for halberds to chop trees.
I got the same result on test. I wish someone with and without the skill could verify whether thats the case in live UOR.
