Back in December I wrote a post about Perception and whether is was even a trainable skill. I think a lot goes into “perception” ( alertness, visual acuity, intuition, reasoning) and the way it’s used by Rolemaster makes it an incredible skill that covers a huge expanse of ability.
But even if you could make an argument (and many did) that perception is a trainable skill, it’s vast multi-disciplinary scope is harder to argue. For instance, while a fighter may be able to perceive an opponents sword skill, the apparent movement of troops or even a carefully laid ambush it’s harder to accept they might be able to detect a trap or secret door if they have no relevant experience in such.
Doesn’t that make sense? No matter how alert or perceptive you are, you can’t perceive small details or glean information on a subject with which you have no skill, training or education. I consider myself a perceptive person, but I can’t look at a horse and draw any conclusions the way Peter could. In other words, perception should be tied to subject matter fluency.
Of course one solution is to add a ton of perceptual sub-skills: perception: reality distortion, perception: traps, perception ambush etc. Of course the list is virtually limitless and would add dozens of new skills to an already bloated system.
With that in mind, I’ve been trying something new and it’s working quite well: I’m using the SKILL RANKS of the appropriate skill/lore as a bonus or modifier to the perception check. If there are no ranks then it’s -25 (along with any difficulty modifiers). So the Thief with 18 ranks in locks/traps gets a +18 bonus to their perception roll related to locks/traps. It’s simple, makes sense and once again creates a use for skill ranks as a measure of proficiency.
