I had read that tweet before and was pleasantly surprised to see Mashima saying it is the same spell and asking the fan to check Rave if he wanted to have a look at it. If it is as strong as Shakuma's, then it is the strongest spell in FT used by a human surpassing both Tenrou LFD roar and Hades Amatersu 100.
