Heph Dragon Farm / Carry Method with Meridionalis
Heph dragon is easily one of the hardest radars in A3 for most teams owing to the fact that he has a 15 turn skill delay and 7 turn timer. Since most damage enhances come in the form of inherits for most teams, this means your attempt to kill him will be done without a spike, on a 7 turn timer, with few actives, and a required 79M damage.
Most teams solo cannot deal with this making it very difficult for solo UA3 players to achieve their Heph Dragon drops.
