finished all the other Silver quest and about 3 Golds. But Thief Silver gives me headaches.
It seems that one needs to find 3 attack-booster to kill a lvl2 guard without quaffing 2potions. Then it takes sometime to reach the lvl2 guards, which is also a waste of black space...
I mean, i get the impression that one must scum for the right setup and then make no mistakes in order to beat the dungeon... And this is getting on my nerves

So if anybody has a strat which is reliable, please share.
But also hints if the other chests are worth the ressource investment (the other lvl1 chest with GETINDARE is nice) would be helpful.
