I pull more minors when I am casting EQ in larger groups of monsters, such as level 1 and 2 of the Tokuno champ spawn. I normally walk away from those first two level with 4 or 5 minors, others that cast wither and EQ are getting more during these two level of the spawns. During the 4th and 5th levels I will get at least 2 or 3 minors. The character I use for this is a bard [120prov] elf wearing the Song Woven Mantle, 100 luck. There is no more luck on this character as the rest of the armor is for LRC and high resist. So far I got one mempo.
Now my friend, "tiger" has four, his secret, cast wither and EQ, die a lot and, lure huge herds to others as they fight them, cast wither and EQ, cast wither and EQ, cast wither and EQ. He is running with zero luck, the RNG loves him. So go kill those monster folks!
