I did some quick research with the items I have matching sets with.
When combining Mynas Helm of Thoth with Mynas Plate of Thoth. I received +1 extra Crit.

When i combined Mynas Helm of legend and Mynas plate of Legend . I received + 1 extra Health Regen. That could be from the str gain but idk

When I combined Pharaoh sword of Thoth and Shield. I received +1 Crit +1 Dmg and + 2 DPS Extra.

I guess You can gain benefits from both Thoth and Legend items. By wearing one set on your head and chest and the other shield and weapon.

This is just a shot in the dark. Other then this I have no clue. I could be totally wrong.
