Okay, apparently there is no Open Lock spell,according to a developer at Quakecon, because well, developers are lazy and can't figure a way to balance magic, so they just nerf bat magic.
If you look at the lock picking in the ESO videos, you will see there is a timer when you are trying to pick a lot. The harder the lock, the faster the timer. So as an example, if you have a minute to do a very easy lock, you might only have 10 seconds to do a master lock. So, I suggest the Time Lock Spell.
Time Lock Spell: Cast on self. Lasts 60 seconds. During that time, when picking a chest it doubles the time you have to pick a chest.
What do you guys think?
