add Temp solution to siege reward

[quantrieu 15]

Hi admin!

Lately, I've noticed that very few people are participating in the Siege event. I kindly suggest adding a Temp Solution potion as a reward to help motivate players. Of course, I'm not asking for a high drop rate—just around 2 potions per siege would be enough. I believe this would encourage more people to join the event and increase online activity. Thank you to the game management team."
