The "sober view" is a difficult technique only derived from the suprising lack of booze in the hero's/heroine's alchohol system. This can be seen as a good thing if the said state is maintained for longer than the time it takes to reach the next tavern, enhancing wit and bargaining prowess of a "sobered" hero/heroine. The experience of the "sobered state" can be a little challenging due to bordom and thirst at times, but once mastered, the user of the skill has the ability to fully utilise their "grey matter" in the bargaining process, selling items for higher rates and practically relieving traders of valuable weapons and armour.
Level 1~5 honing your skills of sober intuition, once mastered you can tell if the merchant has a buzz. If he does lets make a deal. Make him deal with you taking advantage of his dull wit and senses.
Level 6~9 now the clandestine catylest of intoxification is your 6,7,8,9th senses. Get em!
Level 10 your senses are sharp, a rapier wit, time to take advantage of all this time spent training, and diligently waiting for the perfect time to strike, swindle, stab, steal, deal, coupon, and get something special from these crooked vendors!
