Ah, the wizard-relegated, much maligned knowledge skill. All too often does the knowledge skill either get pushed into slots the player has little care for, or reluctantly doled out amongst the party in fears that something critical will be missed along the way. We received a tip a little bit ago to get back to the Top Ten lists I used to do, and Spenser nudged me along with this suggestion.
In many cases, you can use this skill to identify monsters and their special powers or vulnerabilities. In general, the DC of such a check equals 10 + the monster’s HD. A successful check allows you to remember a bit of useful information about that monster.For every 5 points by which your check result exceeds the DC, you recall another piece of useful information.
