UC doesn't open chests

Does the Unlocking Cuntrip open ALL chests and doors, or does it depend on MA?
I've started playing my first battlemage (I'll probably make him a Vorpal bunnies breeder like I thought before), and I'm facing a certain problem. When I played mage characters before, I usually chose the "sold your soul" background for MA boost, now I'm playing with low MA (30). And I keep running into the same problem- chests don't open. Not the two chests in Dernholm palace, not the one with the Jewel of Hebe in the Panarii temple of Tarant. Is this because of the low MA, or is this some kind of bug?

 

Your MA has to equal or surpass the difficulty rating of whatever it is you're trying to open. If that weren't the case I'd probably invest in Unlocking Cantrip for all my characters, even techies.

 

So, can we unlock everything with UC and 100 MA? (Except magically held ones, of course)

 

I believe so. Most of my magical characters that learn UC usually have 100% MA and I have only run into this problem early on with the low MA. So I think it will open all locked, not held, doors with an MA of 100%.

 

UC uses a simple lock difucility / MA formula. If the MA is bigger, you are in. A simple Disperse Magic or a good axe will get through the magicly held ones.

 

Hmms.... Thanks.
