What is your suggestion?:
I am suggesting that there is some sort of check box or a "I got it, Do not show me this again" option when entering the Karuulm Dungeon. This option could be added on the second dialogue text box asking you to acknowlege the risk of entering the dungeon. If you were to check the option, Do not show me this again, you would just be able to click the barrier and enter the dungeon regardless.
Is this in OSRS?:
Honestly don't know, but there is something like this when entering the wilderness is really where I got the idea.
Has this suggestion been accepted already?:
From what I searched, No.
How would this benefit Alora?
I feel this can benefit those players who are just trying to get to their task quickly and to surpass the dialogue when entering the dungeon. I feel this wouldn't change anything but benefit those who already know the risks of entering the Dungeon. The text would still appear for a normal for players who weren't aware of the risks unless they have clicked the option.
