Jormungand

Yotsmungand (Jörmungandr) is an evil magic used by Dark Mages in the games Fire Emblem: Seisen no Keifu and Fire Emblem: Thracia 776. It is a standard dark tome, similar to Flux in later games, Although it should be noted that it has far higher attack than Flux. In Thracia 776 it also poisons the enemy it is used on (provided it hits)
