Chadul
Temuair Master-AB99
Chadul is a hunting ground where Archers thrive.
The Leafhopper Chirp, an optional Bug Event reward, also comes in handy here by removing Suain. It is not mandatory, but it helps a ton with survivability.
Archers
An Archer with Star Arrow is one of the strongest options for hunting Chadul.
Star Arrow's Light damage works especially well here and can keep the floors clear quickly with enough damage.
Light Damage
Light damage is very effective in Chadul.
If your character can take advantage of it, using a Lumen Amulet and applying Fas to the monsters can increase your damage considerably.
Summoners
A Summoner with high MP and a Lumen Amulet can also hunt Chadul effectively using MSPG.
This method is less safe, since repeatedly using MSPG and refilling your mana can cause your health to drop quickly. Careful HP management is important when hunting this way.
