Hi, i think about this idea since 2 months so i decide to tell you a great suggestion.

Add a %odd for all treasure vault in arcade may become event level.
They become :

- Creepy Apocrean graveyard
- Owlite castle with Black Kat.
- Gritchlin mountain
- Garden of tortodrones
...

This change in arcade may be effective only during week-end.
(from Friday 0.00pm to Sunday 0.00pm)

Pro :
- All player who miss a event may have a 2nd chance to have
a Obsidian weapon or other event items.

- Fell the thrill of unknown when your go into a random deep.

- Easy for developer to add this into the game.

Con :
- Low level knight may die in those levels. (see restriction to solve it)

- Event item may become more common.

/!\ Restriction :
-The party is locked when you arrive into a event level (exactly like normal treasure vault)

-Low level player never find this level (for their own protection) only 4 star player (champion) may have
access to this feature.

Tell me your fell about this idea. (cross all fingers and make a wish.)
