Please give them to me. I have zero. I love raids. I love trying the best defense out there. I love experimenting with my heroes, finding new and interesting synergies between them. I do mono and I sometimes replace one hero for another one at a time and see and learn whether they are a good team or not. For 3 years in the game, I only managed a measly 23,047 raid wins under my belt. I try to open raid chests at least 3x a day. They give me iron and food for me to hoard at my Hero Academy and Alchemy Lab (previously, food was stored in my TC20), as well as other goodies that drop every now and then. It also speeds up the appearance of elemental chests, which I chase since they give emblems and whatnot. Unfarmable ascension materials are just a cherry on top of that. Moreover, raiding gives me valuable experience on how to combat the best defenses in the mid and upper diamond arena. That is the main reason I have zero raid flasks.
I dunno if I have items eligible for recycling. I only have a few WE and titan flasks. I use them when necessary, i.e. farming during Atlantis Rising, Valhalla Forever, the monthly challenge events and against rare titans (or even regular titans that are close to escaping). I really dont have general items. But I have tons of other mats. I would love to trade off my 21k rugged clothes. I really dont find any particular use on them except TC19, which is very food and recruits extensive. I’d rather use my practice swords (currently queued at 5,282 at TC1 and I still have 1,391 unused swords) as they are pretty food and recruits efficient. Maybe I’ll burn the rugged clothes once I have depleted my swords. How about training manual. I have 29,882 of them in my inventory and I have yet to find a use for them. Common herbs? I have over 31k of them.
