Just to echo the above - love the design and references to the old Ed Hunter game but some of the scaling seems much too high for 3* characters, especially The Sphinx. There might be a workaround for the stun-blocks (although I haven't found it yet) but the characters do a pitiful amount of damage. Ragnaroks on S. Chopper seemed to help the other waves but my game has just been stuck on this wave for ages now.
Not too bothered about Cosmic Fools (although I would have liked a set of Firestorm and Rush) so will focus on Infinite Dreams and revisit Ed Hunter at a later date either when there is a suitable talisman set available or stat scaling is adjusted slightly.
