Ok it's about minion sweaping...
If she has twin strike (she should) that's two minions a round.
MC monk adds 1/encounter a dead minion or more depending on level or damaged monsters.
Dilettante Power (five storms) = 1/encounter closeburst 1 enemies only
-She should go STR/DEX or get Martial Dilettante and change the ability score to WIS. With Versatile Master that is "at-will close burst 1 enemies only" all day long.
Why would she want to do that? Monk powers are dex based, and her dex is higher than her wisdom. Martial dilettante only works for martial powers, and monk powers are psionic.
