Upon casting this spell, the druid is able to detect snares & pits along the 1” wide by 4” long area of effect path and thus avoid such deadfalls. Note that in the underground only simple pits, not all forms of traps, would be detected by means of this spell. Outdoors, the spell detects all forms of traps — deadfalls, missile trips, snares, etc. The spell lasts 4 melee rounds for each level of experience of the druid casting it, ie. 4 rounds at the Ist level, 8 at the 2nd, 12 (1 turn plus 2 rounds) at the 3rd, etc.
