[Ritual Mastery] 8 [Feat] Summoning [Description] 
You can bind summons to a task and a location provided the location has some magic able to fuel them, this construct is summon as usual at the location and then exist there indefinitely no longer counting as your summon, for any purpose, though it is still an arcane link to you. It serves it purpose until destroyed, or its magical energy source destroyed
