So, today i forged my 87th Weapon frame. Form all those i dropped the Meyrin, Rasmussen and Bergusia Shaders multiple times. BUT not a single Satou one. Yes Im doing the Izanami Forge, YES Im only forging Bow and Pulse Frames, YES Im getting it to Max Temper every time. But not a single time the Satou drops, the others drop pretty often. There is something wrong. Edit: Yes im also using the Polymer each time
