Summoner's Concentration

You have grown particularly adept with a certain kind of magic. Concentration on summoning spells (such as Summon Fey or Conjure Woodland Beings) and spells that change the properties of a weapon or piece of ammunition (such as Magic Weapon, Ensnaring Strike or Flame Arrows) is second nature to you.

• Increase your Intelligence, Wisdom or Charisma score by 1, to a maximum of 20.
• You have advantage on Constitution saving throws that you make to maintain your concentration on a spell if that spell is a summoning or weapon modifying spell.
• You can concentrate on two spells at once, as long as one (or both) of them is a summoning or weapon modifying spell. When you are forced to make a concentration saving throw, you roll separately for each spell. If you attempt to cast a third concentration spell, you choose which spell to end, as long as either the new spell or the remaining spell (or both) is a summoning or weapon modifying spell.
