• Vanilla armor is forced into levels 1-5
• Non-vanilla armor it's armor level is deteremined, then compared against leather - chainmail - iron - diamond in that exact order for the same armor items, giving an indication of where the armor should fit in the list
• Armor and toughness are calculated from an itemstack directly, taking attribute modifiers into account, hopefully to resolve Does not wear Tinkers armor' Construct #10586
