Polyhedron #30: Dispel Confusion. p29. ADQ: Can spellcasters (or for that matter, monsters with innate spell powers) see through their own darkness effects? ADA: No, not even the caster can see through darkness without other aid, such as true sight. Darkness is usually used to confuse the enemy while the caster escapes.Dragon #153, Sage Advice: Q: "Can a light or continual light spell be used to negate the darkness ability of a demon or devil?" A: Yes, on all counts. Each of these spells can negate darkness of any sort, though a light spell will "go out" immediately after negating such darkness, while the continual light spell will last. Light or continual light spell will negate only one darkness effect at a time; thus, if there are two darkness effects in the same area, the area remains dark until two light effects are used.Dragon #33, Welcome to Leomund's Tiny Hut: Light: The DM guide says a figure will be at -4 on “to hit,” saving throws and even armor class. I find that to be too drastic of a penalty; I’d suggest -2. Also, I think the effect wears off since the figure can move away; it is like a flash bulb going off in your face. The effect wears off in 1-4 rounds without resorting to magic. The eyes are not damaged in any way! -Lenard LakofkaDMG. p.145. Gem of Brightness. Although this glare lasts but a moment, all creatures within its area must save versus magic or be blinded for 1-4 rounds and thereafter suffer a penalty of -1 to -4 on hit probability dice rolls due to permanent eye damage. This use expends 5 charges. Dazzling or blindness effect can be removed by a cure blindness spell; eye damage can be cured only by a heal spell.
