Does anyone know what the benefit is to upgrading your weapon? Also how long does it take to get a full load of Rigelians. I only just made the doughnut torture device on time and I want to get ahead as quickly as possible for this lot.
Upgrading your weapon means your tapped radius when tapping Rigelians increases (not very much but nails don't seem to be used for anything else).
A Rigelian will spawn every five minutes until you hit 50 Rigelians in your town, so you'll hit the maximum amount of Rigelians every 4 hours 5 minutes.
