UOSir

an abbrevation of "UO Static Item Remover", was developed by a guy calling himself "Darus" and, according to his website, obviously abandoned in 2001. But it nevertheless works well as long as you remain on the first statics map (statics0.mul). IT HAS NO SUPPORT FOR THE "NEW MAPS" like Ilshenar, Malas, etc.! Nevertheless it can be used not only to remove single items from the statics (a tree here, a rock there) but also for cleaning up whole areas. But what we think the most important feature is to export rectangular areas from the statics for re-importing them as dynamic items.

What would a player have use for that?

Remove a tree? *confused*

Is it a hack?

For a player, nothing.
For the admin, it will allow them to change the static map for events and such.
