Fire Cave/1.03

Plaguelords
Fire Caves only produce Pyrohydras but do allow for Eye of Flames to be produced from the Temple of Eyes.. Although Pyrohydras have the potential to do massive damage against all targets, they are let back by their high cost, terrible weakness and being over shadowed by other units in the Plaguelords army that can generally do more with less. Things aren't made any better for them when you take into consideration that to upgrade to a Fire Cave is to loose your standard Hydra Cave and with it the standard Hydra. Because of this, you may actually want to fore go upgrading your Hydra Caves into Fire Caves, although you will still need to upgrade at least one in order to produce Eye of Flames.

=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.
