"What if they pull back their army once they found out their headquarters is attacked?" Jack asked.
"If they do that, they will risk facing harassment from all the guilds and players inside this country for at least a whole week," John replied. "A guild army summoning crystal has a one-week cooldown. Once they recall their army, they have to wait one full week. No matter how good they are, they won't be able to conquer other guilds' headquarters without their guild army. Hence, they can only try to invade again after the cooldown is over. But can they survive that one week? Once the bounty quest was issued, every player and guild will be gunning for them for rewards."
"Also, if a guild becomes an enemy to the country they dwell in, they won't receive any protection status even after losing sufficient power," Peniel explained. "They will only enter protection status if their guild core is broken. Even then, the period of their protected status will be halved."
