Special Agent Rosenstein

Rosenstein can be obtained by trading in 75 "Magic of Tesla Energy" books. These in turn can be obtained by trading in Goliath Slayer (Captured Destroyer) or Armour Breaker (Menno Doomerville tank) convoy tokens at the quartermaster, at the rate of 3 tokens for 1 book, or at the Catacombs shop at the price of 48 diary pages for 5 books.

Rosenstein's attack is a small AoE Tesla blast with perfect accuracy; it never misses no matter what the Evasion score of the target, and his Accuracy stat isn't even capable of being trained higher. Compared to the baseline hero Captain Walker, Rosenstein's weapon range is the same as Walker's without any range boosting training/equipment, and his firing range is about 1/3 of Walker's. With roughly the same damage-per-shot of Walker at equivalent training/equipment levels his overall raw DPS is lower, but as mentioned above Rosenstein never misses.
