Anything is possible
You should be able to do something like this:
- Mob gets killed in Crushbone
- In sub EVENT_DEATH, define a Global Variable
- An invisible "watcher mob" in Oasis keeps checking to see if the Global Variable is set
- Once the watcher mob sees the variable has been set, spawn the next mob
- Have the spawned mob delete the Global Variable (unless you want to increment it, to have separate stages)
Hope this helps point you in the right direction
