Question Breaking Objects - Trigger or coding?

I looked through the dg-scripts and couldn't find what I was looking for. 

Simply, I want to have an object, say a chest, that has no key, is locked but can be bashed/broken open.

Is there a script/dg-script that will help me do this or do I need to do some coding to make it happen?

Thanks for any pointers in the right direction.

Here's what I would do:
1. make a mob "the chest", with low level but serious amount of hitpoints (too many to die in one hit)
2. add a hitpercent trigger to the mob, with 100% as the level.
3. This trigger should load an object called "broken chest" and some valuables to the room, and then purge the mob.

This will result in the mob being "attackable" and it will immediately trigger this exchange when attacked.
