I was just wondering....since we only get one use for one pet in the sanctuary per day....

what if you could do upgrades to the building to get one extra use per upgrade?

Im suggesting only to level 4 or 5, with some limits that apply per day

ie:   level 2 - 2 uses, but only one per pet per day.... level 3 - 3 uses, limit 2 per pet  per day....level 4 - 4 uses, limit 2 per pet per day....level 5 - 5 uses, limit 2 per pet per day

It would give us extra options without overly increasing the power of the sanctuary

what do you think?

bump  :)

I think that upgrades like this have been suggested before and were never implemented because they're considered to be over-powered. They're essentially free energy potions.
