One often lamented thing about D&D is that many potential adventure situations can’t really be done because there’s a simple single spell that can solve the whole problem. And with 3rd Edition this is definitely the case. Continual Flame? Detect lies? Zone of truth? Teleport without error? What the hell were they thinking?! Any time you have an idea for a spell because “wouldn’t it be neat if you could do that?”, you really have to stop and think how this would affect the obstacle it deals with in the long term. Teleport without errormeans the party will never have to prepare for the return trip out of the dungeon or back to civilization. Any time they face real difficulties they can instantly go to a city or castle of their choice with a single spell. Are you looking for a traitor? Get all the suspects together and have them say “I am not a traitor” after the cleric rested and prepared detect lies. This is such a problem that seemingly every second high level dungeon has magical interference that blocks teleportation and every villain wears an amulet of mind shielding. It’s a ridiculous situation and probably contributed a good deal to 3rd Edition and Pathfinder adventures being overwhelmingly linear combat. And to make matters worse, these games let you very easily make scrolls of all spells you know and even wands with 50 charages. One knock spell isn’t a disaster. A wand that holds 50 knock spells is an entirely different story, though.
So this week I went through the spells in the Basic and Expert sets again to see at which character levels certain kinds of obstacles become easily negated with spells. And to my surprise, B/X is actually doing really well in this regard. There are a few spells that are really extremely useful but they are few in number and even those are not making obstacles completely redundant.
With this spell a 1st level wizard can read any unknown script and language. While it says “any code”, I assume this to mean that it can decode any cipher but still will give you only a literal decryption but not tell you the meaning of secret code words and phrases. While you can read any written texts it doesn’t give you the ability to write in languages unknow to you so you can’t use it to communicate across language barriers. Two wizards who both have the spell prepared could do it if they can make their intention to do so clear, but even then it lasts only for 20 minutes.
This spell lets a 1st level cleric sense “evil intentions, or evilly enchanted objects”. Since there is no evil alignment in Basic it can not detect that. The spell only provides a feeling of evil but no specific thoughts and it’s explicitly stated that GM has to interprete what evil intentions means in the specific campaign. This spell is not “find the guilty one”.
This spell allows you to make a torch that lasts until dispelled. Or lost or stolen. I’m not really happy with parties not really having to bother with lamps or torches (or only keeping some as emergency backups) from 3rd level on if a wizard gets this spell but it’s not a real disruption of actual major obstacles.
