Roc and Thunderbird
Dwelling
Roc is recruited in Cliff Nest.
Upgrading
Can be upgraded to Thunderbird for 100 gold per Roc.
Description
Rocs and Thunderbirds are the only flying units available at Stronghold towns. When Thunderbirds attack, there is a 20% chance thunderbolts will strike their target, delivering 10x the number of attacking Thunderbirds in additional damage.
Comments
Rocs are decent combatants by themselves, but only used in desperate situations as it provides no speed benefit over the Hobgoblin or Wolf Raider. Can be built in less than two days from the start if Goblin Barracks exist, making early exploration much easier.
