Iron Guardian/1.03

Temples
Iron Guardians look rather intimidating and for good reason - they have stats comparable to an actual tower that's been garrisoned with a few melee units. They are summoned through the spell "Summon Guardian" at level 3 and onward. Disappointingly, the range of the Guardians never changes, leaving the Iron Guardian with just the same range 8 that the Clay Guardian had. This does mean that it can be easily out-ranged by common missile units, but nonetheless, anything else that approaches it wont be walking away without taking some serious damage, that is to say, if they actually walk away at all! Due to their lengthy summoned timer, they can be used as additional defensive structures in your base and not need to worry about replacing them. They also make great mine defenders, similar to Stone Guardians, but you wont even need build an actual tower.
