So, I have a lowbie Ench that has been practising charming on Oasis crocs. (All my chars are lowbies, highest lvl 22.) She does pretty well on any blue mobs, difficult if even con or just 1 level lower. But it works well otherwise.
The only issue I have is that I have been playing it wrong. I have been playing for my pet to win, as I would with my Necro who I have a longer history playing. I am going to have to try out the Charm a pet-Let a mob or mobs almost kill it-Break charm-Nuke or dot pet to finish off-Charm new pet for sacrifice. It will be different, but I can see how I could almost constantly kill this way.
FYI, her gear was all purchased by earned plat, as I have no high levels to twink.
