Summon Spells Let your mages expend Gems to summon Troops and Commanders that grant your nation greater variety especially by Mid to Late game when most players start climbing into additional paths.

Many of the Troop Ritual summonses would be found situational as they could be spent on other spells and Gear. Many troops work out as Spell magnet (a bag of HP with relative low armour and MR), Counter particulate army, Siege chaff, or line holders that will survive your mages having Lighting/Fire/Ice fall from the sky.

For most spells that summon troop units, for each level, the caster is above the Primary Casting Path required by the spell, It will produce +1 or 1/2(rounding down) additional units for each level of overcast.

Here are the Summons not restricted by nation, that theoretically any nation can cast. This is Broken down by Magic Paths.
