I have a 12/6/2 Wiz/Fighter/Rogue where I used the following link to source out my trapping skills
http://compendium.ddo.com/wiki/Is_my...l)_high_enough
Diables = 56 = good to disable all non-epic traps
Search = 44 = good enough for non-epic traps
For my build I have
28 ranks(inc int modifier) +28 (items/buffs = +4(GH) +2(HoGF) +7(tools) +15(item)) +2 (skill boost) = 58
For rogue I took 1 at 1st level and the other at 14 so I have reconstruct as soon as I could. Rest was fighter in my case.
UMD = its easy to hit 39 with wiz. My toon has
21 ranks (inc -2 cha) + 18 (items/buffs = +4(GH) +2(HoGF) +3(bunny head) +3 (cha stat item) +6 (cha skill item))
