From what it looks like, instead of 2 stats being a requirement to use skills on hybrid weapons, the secondary stat (magic, strength, spirit) becomes a requirement to use/equip the weapon, while the weapon skills purely determined by the weapons stat. so a higher weapons stat would be required to use strength weapons, but from the example given, it looks like there is a small reduction in the total stat points used (Colossal cleave on Evander’s Greatsword requires 120 in Strength and Weapons for a total of 240 points spent. The new method would require 100 in strength to use and 130 in weapon for the skill, saving a total of 10 points)
The way I see how spells on arcanium weapons and strength weapon skills like colossal cleave, it’s very hard to envision what a savant weapon would even look like or how it would function, especially for 4 way savants like myself. I doubt savant weapons would have more than 5 slots to accommodate for rites and spells
Tldr: stats you would need to use strength weapons now lean more on weapons, small reduction in total stat points to use weapon skills on strength weapons, and hybrid weapons that require 3 different stats are uncomprehendible to me
