As you can learn from these questions and answers, this Paizo blog post and some SRD entries, there are many ways to overcome a dark magic.
Banish with light spells
Since light spells have a number of "touches," scattering can be difficult and dangerous. You must find the object on which a dark magic was cast and touch it. When darkness comes from an arbitrary magical ability, you are crazy when trying to work with limited resources, such as: B. Magic Slots to compete against them.
Requires preparation for appropriate action and is generally considered an inferior strategy: Instead of preparing an action for the spell, it is usually better to prepare a damage spell or disable the enemy. When darkness comes from a magical ability, it can not be countered.
Disperse with dissipating magic
Dispel Magic has a medium range that allows you to disperse from a distance. However, it requires control of the caster level and the line of effect. Basically, you must be able to see through the darkness that emanates from an object that you are aiming at with your distraction.
If something grants you Darkvision, such as your race or spell, you can see in normal darkness. However, not in supernatural darkness caused by the Spell Darkness Darkness, and your allies can not see in darkness unless they also have Dark Vision.
Get a light spell of a higher level
Set an NPC to cast a Continuous Flame, which has been increased to level 4, onto your dull gray Ioun Stone. This will appear through all Darkness spells below 4 (namely, 0, 1, 2, and 3) or through spell-like abilities that work like this. This will cost you 25 + 7 * 4 * 10 = 265 gp. Ask your GM if he can buy metamagic spell services. Once you have your own Level 4 magic slots, you can do it yourself.
A simple Ioun torch would not help because, according to the blog post "Illuminating Darkness", it can not even penetrate a simple level 2 darkness spell. Even if you convince your GM that the spell is from a cleric rather than a wizard, Deeper Darkness still means you go crazy.
Buy a scroll of daylight and a few secular torches
The above-mentioned blog post says that even if daylight can not suppress all dark magic by balancing, the default lighting is set to Environment, and you can use non-magic sources such as torches to illuminate your path.
For only 5 gp you can buy a spring-loaded wrist sheath and draw a scroll as a quick action. Ask your GM if they cause occasional attacks and if scrolls are considered "an underarm item": their mileage may vary.
Use "unwelcome halo" instead of "daylight"
As clarified by Mark Seifter, a member of the Pathfinder design team, Unwelcome Halo should be able to penetrate as it uses the same wording as Daylight any Dark magic of any level at the expense of Level 1 magic slot.
Instead of Daylight scrolls, you can also purchase Unwelcome Halo Scrolls, each costing 25 gp. Do you expect to fight dark magic? Prepare one or two unwanted halos, it should not hurt much. Do you regularly fight against creatures with magical abilities like darkness? Buy a magic wand with unwanted halo!
As of August 2019, this solution is completely PFS-legal, but your GM might or might not consider using physical force if you solve so many sinister encounters so cheaply.
Note, however, that the radius of Unwillcome Halo is three times smaller, making the illuminated square nine times smaller. At some point, daylight becomes affordable and can therefore be preferred.
Be a Level 8+ Cleric of the Sun Domain
While Level 8 can hardly be considered a "lower" level, anyone who reaches it and has a Sun domain can use Nimbus of Light, the power of the Level 8 domain.
See the ability Darkness
This ability also allows you to see through supernatural darkness. There are some spells that grant it, there are Tieflings who can accept the talent Fiendish SIght twice, Rogues with Darkvision can take on this Rogue talent, and some very expensive items that are probably too expensive for groups of stages mentioned in the OP Lake grant in the dark.
- Scrolls of unwanted light (25 gp each) and scrolls of daylight (375 gp) reset the light level to ambient light (the default setting), regardless of the intensity of the dark magic in question. Then flashlights (1 SP each) and similar non-magic means can be used.
– If GM allows it, load your scrolls into spring-loaded wrist covers.
- Increased level 4 flame can overcome most dark magic applications. Even if this is not the case, it is not lost, but is only suppressed for some time.
- If you happen to be a Sun-domain cleric and have reached level 8, you're in luck because you have a special power to fight magical darkness.
- If you have Darkvision or can easily get it, supernaturally dark rooms are not visible to you.
- In some cases, it is possible to have the ability to "see in darkness" and ignore darkness altogether.
