Hello there is an idea...
To make wilderness even more active & enjoyable place i suggest you onto adding wilderness keys
Keys should be separated in colors that you will have to dig on certain spot to spawn a boss and will have to kill it to get an loot.
The keys will be dropped only from monsters in wilderness in drop rate 1/30
Drop tables from wilderness bosses should be supplies + some rare stuff
When you kill the boss you will get 2 rolls on table "same as zulrah"
