Hello.players.This is Goldceo.
There is a 12Sky guide to tanking bosses/leeching off LoAs, Heolgo Hall and so on. Hope it can help you.... if you are interesting in the guide, please read up the article.

Heolgo Hall:
Iron Demon & Ghost Commanders:
1. All bosses are now Free-For-All. Good luck getting one.
2. If a boss is following you, DO NOT lure the boss onto other players. This, if proven intentional, is a bannable offense.

Community Maps (Beoho Mountain and Master Maps 1-3):
-(All boss names will be added shortly)
-(Lord of Azraels will be covered in a separate section)
1. Bosses in all community maps are Free-For-All. No grievances can be claimed for other factions “stealing” a boss in these maps.
2. Having an assistant to help guard the boss from other factions will be helpful should other faction members appear in an attempt to “steal” said boss, or also aid in the killing the boss quicker.
3. Do not attempt to “steal” from your own faction, your faction members will know who you are and this can cause some tension between players and guilds, among other things.

Faction Maps:
- (Jinong: Golden Herculean)(Guanyin: Golden Tower Lifter)(Fujin: Toad Hierarch)
- Blue Toad Grunt, Fu, Golden Giant Bell
1. These bosses are free-for-all when in faction maps.
2. Parties to kill these bosses for their respective quests will not work, only the last hit will count and the player who gets it will complete the mission.
3. Other faction players can come in to “steal” the bosses if the appropriate shields are down, some will help out, others may kill them on you, then you as well.
