Lizardmen skinks seem severely undercosted. Pockets of 10 with blowguns cost 60 points and can chuck out 20 poisoned shots per turn.
Per the rules the Skink Skirmishers have poisoned attacks only on their javelins, and javelins don't have the Multiple Shots rule.
It's a little confusing, because the Lizardmen list (p. 7) first lists Poisoned Attacks (Javelins only), but the Blowpipe reference at the bottom of the page gives the Blowpipes Poisoned Attacks. But my reading is that the specifically narrowed Poisoned Attacks for
Javelins only removes the Poisoned Attacks from the Blowpipes. Special rule trumping generic rule.
They're BS3, Blowpipes have Range 12" so usually -1 to hit, and Multiple Shots gives another -1 to hit. If you're hitting on sixes, you can expect 3.3 hits. But they're not poisoned. Javelins wouldn't have the Multiple Shots malus, so 10 Javelins would generate 3.3 hits, including 1.7 hits with Poisoned Attacks. This could be strong if they could keep shooting continually from turn to turn. But I think they will be erased or forced to flee quite soon.
They're not hugely tough, but if they stand and shoot there's not much in their weight class that can absorb that much missile fire.
They aren't especially strong or skilled. So it's primarily their cost which makes their performance seem good. Our Free Company is quite similar, just not skirmishers.
Magic Missiles, Vortexes and any shooting will harm them.
