The SOA buff can be bought for 7500 Guild Coins from the Guild NPC inside the guildbase.
Noblesse Buff is given to the biggest spender of each month (VVIP3). The NB holder decides the time and location of buffing once a day, when the buff is used all players in the same town will receive it. Usually the holder would announce everday the time and location of buff, you may ask others in chat or on discord servers for NB info if you missed the announcement. It is ideal to run dungeons, nests, GGC and sunset cloister during this time to recieve additional loots. (Common time and town of NB buff is during night time GMT8+ 9PM-11PM at Saint Haven)
