I got a swift raid in my fuse lab, but I didn’t have even close to the number of required forges. It was 30 ranger forges and 10 warrior forges, I believe. As a mage, I had no reliable way to get them besides buying them with tower coins, but even if I spent all my tower coins, I wouldn’t have nearly enough. Considering that I’d get rubies rather than gold for selling the swift raid, I didn’t feel it was worth attempting. Maybe I’m wrong.
