I know this doesnt work with Hexed Voodoo NPC's... had a guy L12 at Tormenta yesterday come in and start wacking away at the Molusk I was taking... and he was able to do it no problem (now... this is a catch-22 - if the Molusk turned away to hit him - I'd probably lose the REP I had on him because of the reset... but he would die... so its 'Keep the REP and let him live' or 'lose the REP and let him die...' hmmm
But - for those trying to help Level up a lower Guildie - since it appears the Voodoo'ers still remained Hexed you can hex them and they can swing away without damage... Say Padres Beah or El Sudron first - then Tormenta
Just an observation
