Open lock skill

[RunesOrder]

Due to my bad partyformation ( all fighters and one sorcerer ), I can't use the Open lock skill which I badly need to play the whole game and even now to get further...
By the way, I got away without the skill all the time until the Lower Keep of The Catacombs, never had to use it really, could always force the door open....
I didn't find any scrolls or spells to use as well ..

I'm located at a door where I need the Bent Elven Key in The Lower Keep of The Catacombs. But to get to that key, I need to go to an area where I must use the Open Lock Skill for...


Any suggestions ??

The key is in area 13 ( but can't go there ) and the door at 30.

Second time I play this game, my first excisted out 2 fighters, a cleric, a
ranger and a rogue...
Played the Balders and IWD's, could finish them all with 5 fighters and a sorcerer/cleric

Thanks

Sorry all, read the message " Complete without a rogue? "....
Understand that I must sacrifice my sorcerer for him
Pity wanted to complete the game with them,
