Forum:Blast With Chain Rulings

When "Blast with Chain" is destroyed due to the monster it is equipped with being destroyed, the effect of BwC isn't activated, since the card was not directly destroyed by a monster effect right? Does the same effect apply with monster effects killing the monster instead of simply battle dmg?

Basically, I'm wondering if BwC is activated by anything other than directly destroying the card with methods such as "Harpie's Feather Duster".
