Lightning strike special ability
Thunderbirds have special ability lightning strike, which has 20% probability to occur after the stack have attacked, including retaliations. When the stack attacks, the lightning strike occurs before the enemy has a chance to retaliate. If successful, the lightning strike deals additional damage for the amount of ten times the number of attacking Thunderbirds. The thunderbolts have the same visual effect as the spell Lightning Bolt, and the special attack is also counted as one in terms of immunities.
Heroes with a specialty
- Shiva the Barbarian has rocs as a specialty, which increases the attack and defense skills of any rocs or thunderbirds for each level attained after 5th level and gives them a speed bonus of 1.

Since they are the only flying Stronghold unit, the rocs and thunderbirds usually die in large numbers if they are to be sent to attack the enemy straight away. They should be used tactically and not draw too much damage towards themselves, even if their health stat is the third highest for a level 5. Their defense is also pretty low. Save lives of thunderbirds as the bigger is a stack, the better will be lightning strike, and if there are only 2-3 remaining, damage 20 or 30 will be useless for a battle. Use Cure when necessary.
