Summoning Concentration (General)

With concentration, you can extend the duration of your summons.

Prerequisite(s): Ability to cast a summon monster or summon nature’s ally spell.

Benefit(s): When you cast a conjuration (summoning) spell with a duration of 1 round/level, that spell gains a duration of concentration + 1 round/level.

Special: This can be used with the summoner’s summon monster class feature, giving it a duration of concentration + 1 minute/level.
