A friend asked me about trap DC in EE HH, so I decided to spent some time testing Trap/Door DC there.
I'd like to share the results with you too since finally managed to get the exact numbers.
EE HH test result (tested the first trap behind the right secret door):
Left secret door: true seeing was enough
Right secret door Search: 65 fail, 66 success
Trap box Search: 75 fail, 76 success
Disable: 88 fail, 89 success
Reflex: 66 fail, 67 success
I updated the wiki, but it's most likely that this info will be removed.
I mean this info be moved to not so useful pages like Trap DC/Secret door DC.
