What's Lao's weakpoint? Lao's melee weakpoint is his stomach. Stomach: 55% Cut, 50% Impact, 20% Fire, 5% Water, 15% Thunder, 30% Dragon, 5% Ice

Lao's ranged weakpoint is... his weakpoint. It's only reachable by ranged weapons, and I'll explain exactly where it is in just a bit. Weakpoint: 80% Gun, 50% Fire, 5% Water, 15% Thunder, 100% Dragon, 5% Ice

Why does everyone tell me to attack the head then? Lao's head staggers more often. Newbies think that the extra staggering will slow Lao down enough for them to get a repel, but look at how much damage Lao's head takes. Head: 28% Cut, 20% Impact, 20% Fire, 5% Water, 15% Thunder, 20% Dragon, 5% Ice

That's roughly half the Cutting damage and 40% of the Impact damage. If you can kill Lao by attacking the stomach in 30 minutes, it would take you 60 minutes to kill him with a Cutting weapon attacking the head and 75 minutes with an Impact weapon attacking the head. It doesn't matter how often you're repelling the head, you're not doing enough damage to kill Lao (or repel him, even) in 35 minutes.

However, it is ok to attack the head when his stomach is unreachable (when he's first entering the area).

^ do u guys think this is valid info? I got it from somewhere. i don't remember the lao shan page having this info. might be valuable?
