TIL that Might & Magic Merge effectively lets you put over 60 points in skills via +skill item buffs
Title basically. This applies to both item +skill buffs and hirelings that grant +skill buffs.
I discovered this entirely by accident on my Monk. I have a couple items on my Monk to give me +27 to my Unarmed skill. So I (wrongly) figured that there was no point in raising it past 33, but then I accidentally double clicked and raised the unarmed skill up to 34 points, bringing it to 61 points total.
I was going to reload my save, but then I right clicked on the unarmed skill, and was surprised that it still said +27. Other M&M games would have reflected the 60 skill cap and made it say +26. So I checked my damage, poured the rest of my skill points into Unarmed, and saw that my damage indeed went up.
At first I wondered if I was somehow mistaken and other M&M games allow this to, or if maybe the Greyface mod I was using made this change, so I loaded up M&M7 and did some testing there, but M&M7 indeed limits you to 60 points in any skills regardless of +skill item buffs.
After this I wanted to see just how far you could buff a skill beyond 60, so I did a bit of modding in the game files and gave myself a Ring of +200 Unarmed Skill (far higher then you could ever get in the real game) and equipped it. I gained +400 damage, exactly what you would expect if there was no limit.
