The template is just for type1, your suppose to create your own tiles and place them on it. However, I've marked off some useful tiles spots you could use for their different functions.. Like the rock is a walkable area that regenerates if you made a shovel npc.
Unsure if many people actually get it.. Anyway the pot and sign works fine.. I'm unsure how you'd like it to be improved though.. the spots can't change.. they are built into the Graal system and I only found out the locations :X
