Double Summon (二重召喚, Nijū Shōkan?) is a rare Personal Skill possessed only by a few select Servants, permitting them to simultaneously possess Class Skills from two distinct classes. It is limited only to some of the extra classes, the cavalry classes, and "modern classes" like Gunner, with restrictions making it incapable of being applied to the three Knight classes (Saber, Archer and Lancer) and some of the extra classes (like Ruler, Shielder and Avenger).[1]

Double Summon. The skill possessed by Assassin of Red, Semiramis. It is an underhanded skill that is only invoked when certain conditions are met during the summoning, like a “command input on the title screen”.
Of course, this kind of skill has some restrictions, with the three Knight classes (Saber, Archer and Lancer) and some of the extra classes (like Ruler, Shielder and Avenger) incapable of being applied to the Double Summon skill. In other words, only a combination of the Berserker, Caster, Assassin or Rider classes is possible. However, though rare, a modern day extra class like Gunner can apparently be combined with another class through this skill.二重召喚【スキル】
