The Angel variant of Dober P.D, St. Dober deals huge damage and has a 33% chance to create a Surge Attack that hits units up to 350px away from him. However, unlike other Angel enemies, St. Dober is relatively slow. Although St. Dober’s standing range is shorter than Dober P.D's, it has an Omni Strike attack that reaches farther than him regardless. Should that fail, spending NP to unlock Surge Immune units is a viable alternative.
To sum him up, he is a dangerous threat that attacks and supports at the same time, shredding through your meatshields and melee units.
St. Dober's description refers to the story of Hachiko, a Japanese Akita Inu who waited at the train station everyday to wait for his owner to come home. However, the owner died of a hemorrhage at work. Hachiko continued to wait at the station for as long as he lived, until he died. A bronze statue was made in his honour.
