Ice Cave/1.03.25

Plaguelords
Cryohydras are more manageable than Pyrohydras, as well as possessing an attack type that no other unit in the Plaguelords army has. This makes Cryohydras more viable than their fiery brother and Ice Caves worth that upgrade - which however, costs a lot of crystal to do. Even with Cryohydras around, the standard Hydra is still useful. So don't upgrade all your Hydra Caves to Ice Caves and remember to leave some un-leveled.

=Trivia= -In the unmodified game the AI can't upgrade their Hydra Caves and thus don't get access to the Fire or Ice Cave.
