enchanter charm on live was very unstable at low lv and as they grow stronger in lv their charm began being more stable. the only high lv charm that is unstable is the lv 60 that only last a few sec but the enchanter is being able to pet monster above lv 53
here is lucy data on boltran agacerie that clearly shown that the duration should last betwin 6 to 7.5 min ( duration shorter since we can charm lv 50-53 monster )
