What happened if you have low hp and low mana and tio poison at the same time?

Damn, I just got my Kone+ and Alumic from Aussie because I can't find it in SG. I customised my LED to left red and right blue, mirroring Diablo II colour for health and mana. lol
Any idea where to find roccat Apuri? Any store instock?
