I got the information from some players that these creatures would respawn according to the time of the day the basin is lit, so, during the night you will have some of them spawning after you or someone else lit the basin, specially the ones that start at "midnight" on their names or like the "Brides of night" in Kazordoon. I already tested with some of them (Brides of night in Edron and Acolyte of darkness in Drefia respawned only during nightime) and it worked but I'm wondering is this for real or just coincidental? and if it is, what's the accurate time to make each of them spawn when someone lits a basin?
