Spot Trap

Even the most skillfully laid trap cannot be completely hidden from a person with properly trained eyes. The ability to locate mechanical traps in one's immediate vicinity before they are tripped is called "Spot Trap", and the chance of success may be reduced by improper light.

Spot trap Apprentice: the Character's chance of success is unaffected by lighting

Spot trap Expert: the Character is able to sense magical traps as well as mechanical ones

Spot trap Master: if the Character fails (but does not critically fail), he gets a second chance to spot the trap
