Rowena and the others hold their attacks, as Quinta outlines her plan. You stand resolutely as the dogs draw close, confident in the opera singer's magic. The dogs draw closer, tearing and racing towards you, howling and slobbering.
Quinta begins to move rhythmically, languorously. As she does so she starts chanting a droning, ululating pattern. The dogs stop, for the moment totally mesmerized by what she is doing. Four of them are completely enchanted, but two members of the pack continue to growl and look ready to leap past their pack mates.
Ok, four dogs are indeed entranced by the spell. The other two are still on the attack. The rest of you with held actions are up, dogs are now only 15-20 feet away.
