上古卷轴5 英格尔山峰里最后的铁门怎么开

最后BOSS后的铁门，在跟打架的骷髅头身上有个叫杨格之盔的东西，拿了门就开，此外需要注意的是，如果带了随从的话，也可能导致门打不开。
头三个机关的门：
一个是天空的光，一个是草丛，一个是流水，分别对应鹰，蛇，鱼；

有杨格之盔的铁门正前方坐在王座上的骷髅头上的就是！！拿了头盔门就开了

bug，如果你被派去拿冬堡头盔就会出现这个bug
It is reported that the game spawns Yngol and his helm when you are near his throne. Thus, a possible workaround is to send a follower to retrieve the Helm of Winterhold from the final chest, then backtrack Yngol Barrow and finish Korir's favor quest by giving him the Helm of Winterhold. Then, go back to the barrow, and Yngol and his helm could be successfully spawned.

可能的解决办法：叫随从去拿冬堡头盔然后原路返回把任务交了，然后再回来可能就会正常进行
