I would like to know if you have to cast 15 charms/spells on one lot or can you cast them in another house?I'm doing this to get crystal clear ability rocks .Btw i found this .

I will help you:
If you live in normal hood, than you have to cast 15 spells/charms. Better move to Magic Town!

If you live in one of the three homes in Magic Town, than you have to cast 10 spells/charms. After each tenth, you will get a crystal, or strange root, or giant flowers (use them as end tables) or beanstalk (you can climb on it if you keep it to grow)

When you learn teleportation (purple) it will also count as a spell, however, do NOT click 'learn ability' on crystals until they come to their final growth.

Hope this helps

So the 15 charms/spell has to be casted on one house?

yes, if house is located in main neighbourhood

Thanks a lot .
