Sense Motive DC's in combat

First Post
Ever since I bought the Oriental Adventures book, the additional uses for sense motive have been bothering me. We started using them in our games and the effect seemed weird.

Now we can figure out the level of an opponent with a DC 15, and their full attack & damage bonus with a DC of 25. It struck me as odd when our rogue glanced at an evil cleric in RttTEE and knew right away that she was only level X, so he decided to attack the enemy wizard which was level Y.

So it took 1 glance from across the room to figure out the enemies total level, but after he swung and hit that wizard in melee he still had only a vague idea of what AC he had (lower than what he rolled).

What would a fair DC be for determining an opponents AC?

What modifier would you put if they wore a robe over their armor?

Would you have to see them move in combat before you could guess their dex bonus? If not, would seeing that give you a circumstance bonus?

What if you watched them in combat for a round with someone else?

Why would a high level fighter be so weak in sizing up his opponents (ie. why is this not a class skill)?

Rangers and Druids seem pretty strong in this if you allow an Wilderness Lore check to determine these things for wildernessy type creatures, but it would seem that only a cleric would be able to size up another cleric really well. Of course, a rogue would probably be skilled at sizing up anyone.

Why would a wizard be able to figure out the attack bonus of a fighter with the same DC as another fighter? Why would a fighter be able to figure out the level of a wizard at all?

If you play D&D as something other than simply hack and slash, it becomes VERY important to be able to size up your situation. If the DM knows the only action that will happen upon meeting someone is an initiave roll followed by an attack, then I guess it's no big deal because your only going to run into things you have a chance to defeat.

As a side note (probably for the house rules forum), what the game seems to be lacking is a mechanic for this to take the burden off the DM to constantly create creative and inspired ways of describing the opponents you meet. Obviously, the intent of the game is to 'role-play' this, but for the people who are more talented in 'roll-playing' than 'role-playing' a better defined game mechanic seems to be in order.

I would require it to take a full round action for each thing you wanted to learn.

Thus the Iajutsu duel might take 3-4 rounds during the build up as both Samurai size up their opponent.

An iaijutsu duel is not the same as normal combat. There are a host of rules that are specific to duelling, and the Sense Motive check is one of them.

Sense Motive: Characters use this skill in an iaijutsu duel (see Chapter 6) and at other times when they want to appraise the skill of another character (usually an opponent).

Fighters don't get Sense Motive because they are too busy training themselves to hit and avoid getting hit. They don't care about sizing up somebody. If that's the kind of training you want, you'll have to take a non-core book Feat or a Rogue level. (1 Rogue level can get you up to 8 +/- Int bonus Ranks in Sense Motive, if you're high enough level.)

To determine an opponent's AC, I assume you'd have to see them be attacked. Robe or no robe. DC seems on par with the other DC 25 abilities.

You probably wouldn't have to see a character move to guess a physical bonus. I'd make the DC 30. 40 for mental bonuses.

I like the idea about Wilderness Lore and animals.

Wizards can use Sense Motive on Fighters because there isn't any thing class-specific about the knowledge gained with ranks in the skill. One rank in Sense Motive means the same thing for all characters and classes.

I always liked this new use for Sense Motive, but I haven't seen much use of it in the game.
 

I have an inherent hatred of any skill, feat or spell that provides a PC with purely metagame information. I'll never say, "He has a BAB of X." I might say, "He quite a bit better than you are at combat; you'd guess he could beat you easily in a tournament." Anything else breaks the "4th wall" too much.

D00d, that's a _terrible_ handwave. :)

Furthermore, note that the DCs given (15 to figure out level, 25 for attack and damage bonus) are specific to iaijutsu duels.

I agree with you when it comes to normal combat or other situations. An iaijutsu duel (which is where those particular uses of the skill come from) is a pretty unique situation, though, and one where it doesn't seem out of line to provide highly specific information. It's like being in a chess match, and using a chess-related skill to figure out how to proceed.

Argh, you're right! ;) I re-read the section again and saw the "samurai use these DCs..." bit. Heh heh.

As far as Fighters go, I don't see any other explanation. A level in Fighter means (to me) that you focus your training on getting that d10 hit points, +1 BAB, Good Fort saves, and either gaining or moving closer to the next Feat. Sizing somebody up isn't part of that package.

I'm still going to use the Sense Motive skill in combat (although my PCs never seem to hit the higher levels) in the way Piratecat suggested... I think it's a cool use for the skill.
