Says that the highest trap anywhere on mainland Elantia is -160. True or what?
If true then a combo of (Disarm bonus + perception bonus + Wisdom Bonus) >= 262 should make it impossible to miss one barring a fumble.

Also, if I find a scarab trap at say -70 and disarm it is the scarab also a -70 trap or is it randomly different?

So not true it almost made me laugh. I find traps more then twice as big in minotaurs all the time.

<<Minos are the lowest level critter where I've seen -480 traps. Twice is common, thrice is possible, though most trap types on their boxes top at about 400 in my experience and its just scales I've seen around -480.>>

Check your math.... 2 x 160 = 320, leaving plenty of room for lots of traps between that and minos normal max.

Cause I said twice as big, not thrice as big :P

Men! Always talking about size.
