加入了这个：
Champion’s Covenant
Only the fittest are recommended to join the Champion’s Covenant. Members
of the Champion’s Covenant will find a more difficult and unforgiving world
of Drangleic as they explore Dark Souls II. These players may also have
difficulty summoning friendly phantoms.
好奇就加入了。游戏里就不能提示，加入这个covenant 有什么作用么？原来我一直以
ng++难度在玩。。
