Most spawns are in night time , in daytime too but when rains or storms , night + storm = 10% of spawning very close of each others ( each 64m )

You can lose them with a karve and FULL WIND UP if there isnt a good tail wind you can loose them well , longboats are the best for fight and lose them , best speed and resistence
Best arrows against them are ice arrows , can be killed with 3 or 4 shots
