'evening All,
I did a google search of the forums for "medical"+"onyx" and only found one, locked, thread, so sorry if I missed the answer here.
However, it seems that medical armor with the onyx pack applied doesn't heal the player at all? Am I correct? Is this because the armor has no durability? Sad lesson to learn, wasting an onyx pack, if that's the case ;p
Cheers,
