Gorgorab is a Magic affinity epic from the Undead Hordes faction. He is a fantastic mid-game champion able to carry your team through most content.
Gorgorab’s strongest areas of the game are Arena where he brings a speed aura, turn meter boost and Increase Atk buff, and Faction War where he can revive fallen allies ensuring 3 stars for completed levels. I would only invest books if using in dungeon or FW content. No books required for Arena.
Gorgorab is a great all-rounder and can be played at level 50 with good speed and defensive stats.
