Casting summons into houses

[Jack]

Remember that energy vortex and blade spirit can be cast into a house breaking chest and other impassable items that are not locked down.

For the record, this part is not accurate to OSI/era and will be changed with the next patch. Target-able summons will not be able to be casted into a house region.

Thanks for the guide Ziggy!

This patch note from 1997 says that it was not possible to summon into a house unless the caster is already in the house:

• Summoning now tries to find a valid nearby location. They can only be summoned into a house or ship if the caster is in the house or on the ship.
  

Testing on the demo (mid 1998) confirms that you can not cast an energy vortex into the house, which stays true with this patch note.

Finally, it is still not possible today on OSI to do so, which suggests that this has never been re-enabled since the original 1997 patch to remove it.

So it will stay possible to cast these inside of a house, but only if you are already inside that house.
