Is there a difference between the blindness caused by the sunbeam spell and the sunburst spell?
Both spells are worded basically the same:
Sunbeam
For the duration of this spell, you can use a standard action to evoke a dazzling beam of intense light each round. The spell ends when its duration runs out or your allotment of beams is exhausted. Each creature in the beam is blinded and takes 4d6 points of damage. Any creatures to which sunlight is harmful or unnatural take double damage. A successful Reflex save negates the blindness and reduces the damage by half.
Sunburst
Sunburst causes a globe of searing radiance to explode silently from a point you select. All creatures in the globe are blinded and take 6d6 points of damage. A creature to which sunlight is harmful or unnatural takes double damage. A successful Reflex save negates the blindness and reduces the damage by half.
Sunbeam has a Duration (1 round/level or until all beams are exhausted), whereas sunburst is Instantaneous.
A spell’s Duration entry tells you how long the magical energy of the spell lasts. (PHB pg. 176)
Timed Durations: Many durations are measured in rounds, minutes, hours, or some other increment. When the time is up, the magic goes away and the spell ends. If a spell’s duration is variable (power word stun, for example) the DM rolls it secretly.
Instantaneous: The spell energy comes and goes the instant the spell is cast, though the consequences might be long-lasting. For example, a cure light wounds spell lasts only an instant, but the healing it bestows never runs out or goes away.
Sunburst has a duration of instantaneous, so the blindness is permanent if you follow the rules above. The magic comes and goes but the consequence persists. Is that right?
For sunbeam targets in the beam are blinded, but is it: a) a casting of blindness like the level two spell, which is a permanent duration; b) a blindness condition that ends when the spell's duration ends as per the rule for spells with a timed duration; c) a blindness condition that is permanent?
What's the best way to handle the blindness caused by both spells?
