It also doesn't hurt people who just walk around to the back of the chest and cut a hole in it.You're fixated on attacks when other actions would work just as well. Tying a piece of string around the tripwire should be effective and incredibly unlikely to trigger the trap unless it's intended to kill mice.First: the positive. I like the "detecting magical runes is easier in darkness" bit.However, this is probably the one that needs the most information, yet you've given it the least. How does the spell detect creatures? Is it visually based? Where is it looking from? What specific thing is it keyed to attack? How good is it at seeing past disguises? Can it see in the dark? Can it detect creatures through solid impediments? You don't have to specify this stuff, but a DM needs to have thought it through.Why can't thieves' tools disarm it? Is it really unreasonable to assume that there are mundane countermeasures to magic?Example: A necromancer has inscribed a symbol of death on his spell book. The PCs are going to pilfer it because they're not high enough level to confront him directly, and having him unable to use his best spells twice is a pretty substantial weakening.The spell triggers is "anybody but me looks at the book from within 17 feet and 5 inches".Because the PCs are high level and have sufficient information gathering skills (or sufficient paranoia), they know the spellbook to be magically trapped, but they can't get specifics.What can players actually do except stand 120 feet away from the book and cast dispel magic?And the answer comes down to those questions above - how does the magic detect them and trigger: can the PCs turn off the lights and then simply pick up the book? Can they wear an evil necromancer disguise and pick up the book? Can they pre-emptively trigger the spell by making it think there is a target creature nearby without risking themselves (the spell just says "creatures" trigger it, so technically throwing a bug with compound eyes at the book should trigger it - and if the spell is visually cued, how does it tell if something is a creature)? Can they make their way to the book while pushing a pavise to hide behind? If they get close enough without triggering the symbol, can they deface the symbol and deactivate the magic? Or just shove the book into a box and close the box?Answering those questions makes a magic trap something fun that you can use with abandon, instead of "magic traps suck, so only use them to make dispel magic a spell worth knowing"</blockquote>
