Right now when you change channel/map or warp to send quest you will lost your Sacrament buff randomly. Seem like IMC can Fix it in KR already. But they not fix for us yet.
So
After I try for awhile. If you unequip some armor before change map/channel you will not lost a buff.
For EX
my low lvl char need to un-equip Cafrisun Armor(body) Before change map for keep buff.
my high lvl char with all white armor(no stats) never lost buff.
That’s all I know. You can try by yourself if you have this problem.
