"The Shadow Hornet unleashes two deadly lightning attacks and a devastating sonic boom. Unlike regular hornets, this one can be used for the benefit of mankind."
The RS-B17 Shadow Hornet is the Tier 10 reward for the 14th Boss Strike event, Yuzul the Raptor Trainer. It is almost identical to the RS17 Shadowwasp, but it is less vulnerable to damage, has 10 more HP and the Forked Shock attack can be targeted. However, the Shadowwasp has better resistance, does more damage on it's Forked Shock attack and hits an extra unit. Nonetheless, it is about just as good as it's sister unit.
Another advantage this unit holds over the RS17 Shadowwasp is the heal time - nearly half that of its counterpart. Moreover, it is fairly easy to get to Rank 9, but not as easily as the Shadowwasp.
As it stands, earning 3 of this unit could be beneficial to future boss strikes, especially against Silver Wolves and Rebels, because it sits nicely in the last row, with its attacks being able to decimate the front row units (esp tanks and other vehicles), with extensive attacking coverage (hitting both air and ground units over a wide perimeter). It is strongly encouraged to guild members to try to earn as many of this unit.
Note: These units are ordered by first appearance. The Boss Strikes in which these units got released are noted in superscript. For a list of all Boss Strikes, click here.
