Dark Assassin appearance stone.

i recently acquired a dark assassin appearance stone and i have some questions about it. first, how do i use it? just click on it and it will change my armor style, or do i need to do something else? second, i still dont have r99 armor, but im afraid this item will desappear when the event ends and i wont be able to obtain eternal meanwhile. the appearance stone will stay even if the event ends? if it ends... thx

 

click stone use it on armor and done.

the parts are coming from the tarot thing. that means that you can always have the chance to get it since that tarot thing is here to stay, it is not part of the 10th anniversary event. and by the way, even if it was, you could buy 2 appearance stones, no? :d use the one on seraph and later the 2nd on eternal.

 

and by "armor" he ment main one, be tunic, leather breast plate, or breast plate.
