Recently I had a desire to do saradomin GWD (commander Zilyana), because of the interesting thing, to try something that I had not tried, and because I saw that it appears in the collection log, after that I prepared, look for everything I need for the fight and to enter, well, I tried to enter the saradomin area with ropes, mithril grapple, and everything that you can imagine to enter and i didnt got it, so I want to know if it is a bug, why it cannot be entered or what do I really need to enter?.
note: my sponsor rank is Legendary so i don't need KC to enter.
