Is there any way to use/abuse the 'Sunlight Powerlessness (Ex)' weakness of creatures? I see it on a couple things but I never see it being exploited. A torch would not trigger it. Would a sunrod? Or could a simple silent spell enough to create a 'sun' or other sufficiently bright light to trigger the weakness? Or would a Major Image be needed for the thermal effect? Or is there a magic item I could use?
Thank you in advance,
Basically you need something that explicitly says it acts as natural sunlight. A sunrod or illusion will not cut it.
Alchemists can get the Sunlight Bomb discovery.
Bottled Sunlight works when smashed.
Those are all I could find; it's largely meant to interact with actual sunlight.
