Hello I am fairly new to Lizardmen and I was wandering whether should I buy some Skinks.
Which is the best build for the Skinks? Javelins or the blowpipes?
Also which is the best unit size and what is their main role on the battlefield?
Yes you should buy some skinks. I would get two boxes.
Both skirmishers with blow pipes and regular skinks with javelin and shields have there uses. With the two boxes, make 20 with blowpipes and 28 with javelin and shield.
Normal unit size is 10, or close to it. The skirmishers are there to hunt monsters, chariots, and anything else with multiwounds. The regular unit is there to die. They get in the way and set up charges for you.
I am right 94% of the time, why worry about the other 3%.
I like using chameleon skinks to hunt monsters and war machines and equip javelins on my regular skinks because I face a lot of other (better) skirmishing units in my arena.
definitely a mix of both is the best when you are not tailoring the list one way or the other. The blowpipe skirmishers are just great as sirkentley has stated, they apply a lot of pressure to any unit that is high toughness or low model count, with a low armour save. Skirmishers with javelins and shields are probably a little too expensive for their effect but they can be very useful against low toughness low armour save unit (ie golbins, skaven, elves). Skink cohorts are useful as redirectors, speed bumps and as a kroxigor delivery system.
Every skink unit has its uses and its always good to have variety in the army to be able to cover as many aspects of the game you may come up against.
Skinks are a great unit. Use their movement, which is nearly as much as some cavalry, to be really fast and be forerunners for the saurus. They can make good screens (javelins) or flank harriers. I use both, but more Blowpipes, in units of 12-20.
