Seraphim T2 Amphibious Hover Tank on standby
The Seraphim T2 Hover Tank, nicknamed the Yenzyne, is a Seraphim unit. It is a direct fire unit.
Like many Seraphim units, the Yenzyne has most in common with its Aeon counterpart, the Blaze, sharing the same build costs and build time (but having a higher HP). Its shorter range and MUCH lower rate of fire (ROF) makes it a pointedly inferior unit, arguably the weakest of the 4 amphibious T2 tanks.
While there are some situations where this unit can be useful used by itself, despite its weaknesses, it is better used in combination with the Zthuee, which also hovers; THIS produces a force to be reckoned with. This combination gives you area of effect, greater range, and higher DPS, which is enough to compensate for the Yenzyne's rate of fire. It may even help to throw in a couple of Iashavohs to provide Anti-air support, as they also hover.
