Summon Skeletons is a spell that summons allied skeleton warrior minions. By default, the player can summon up to 5 skeletons at a given time. This limit can be increased with gem level, certain passive skills or items.
Feeding Frenzy Support – Skeletons warriors can use the Dash skill. Skeleton mages will not.
Dead Reckoning – Converts your Skeleton Warriors to Skeleton Mages. Skeleton Mages cast ranged fire, cold, or lightning spell projectiles. They can be modified with support gems such as Faster Casting Support, Spell Echo Support and Awakened Spell Echo Support (which states This Spell and Minions have (55-59)% more Cast Speed in-game), etc. However, according to the dev, the Skeleton Mage cannot benefit from Final Repeat of Supported Skills has 20% chance to deal Double Damage
Spell Totem Support – When Summon Skeletons is supported with Spell Totem Support, the totem will continue to cast Summon Skeletons even if the maximum number of skeletons has been reached. Older skeletons will then be replaced by newer skeletons, possibly switching target.
Summon Skeletons CANNOT be supported by Unleash currently.
