Extra Summon

Extra Summon is a Talent in Ars Magica 2 that, when unlocked, will increase the player's Summon Cap by one.

Extra Summon is found in the Occulus's talents tab and requires a red Skill Point to be unlocked.

Summon Cap
Ars Magica 2 allows the player to acquire partners thought the use of a Summon or Charm spell, or by befriending a Light Mage - if the Mage Posse talent is unlocked. The amount of partners a player can have is normally limited to one (Most likely for balance and stability).
