Same as used with Dragons, however they have ability to burn you with Firebomb. Be careful as they usually spawn near dragons and dragon lords, they're more annoying than dangerous, but can give you a free trip to temple if they combo with a dragon, it's better to make them run by lowering their hp to focus on stronger creatures.
Knights: Try to kill them as fast as you can before they spit fire fields on you, if you get surrounded cast exori or exori gran, as this will make them run and clear space for you to run, not really worth hunting as most will be empty or yield low amount of gold.
Paladins: Try to kill them as fast as it is possible also avoid their waves.
Mages: Just use wand and exori frigo/vis to kill them as fast as you can.
