Real OG might remember the recall stone, although it never really worked back in the day. It used to be a netherbrick that was supposed to teleport you back to base after placing and standing on it. I believe it was 10 Gold and single use only. If a huge rush is happening and you are too far away from the base this would give you another chance to try and defend the nexus. My suggestions are: Cost: 10 Gold Stone disappears after use, leaves behind a stone button on the ground (or someother kind of mark) Doesnt work while in combat (15sec) Time to recall is 10seconds Feel free to add something!
