during the survival rings:blades quest if you stand in the twirling blades after about 15 seconds the dmg just stops. not sure as to why but makes the quest a whole lot easier then having to run around.

Yep and if you abandon the quest and ask friend to share it before the progress bar reaches 100% you will also get the achievement done.
