slann
focus of mystery,focused rumunation,becalming cogitation
cube of dark, cupped hands,-470pts
This slann is not legal because it has 2 arcane items. You are only allowed one item from each section. Also, you don't appear to have a BSB in the list, so you should find 25 points (from dropping the illegal magic item) to make the slann a BSB. Also, you have to declare which lore the slann is using at the point of creating the army list. I recommend the lore of life.
heroes-
skink chief LA,sword of strife,charmed shield,luckstone-107 pts
Why even bother giving this guy a reroll to his armour save when it's a mere 5+? Save yourself 5 points or give this guy a better armour save first. If you want him to live, the Armour of Silvered Steel and a Luckstone is the best you can give. But he's a skink. Don't expect him to live
skink chief LA,ogre blade,enchanted shield-102 pts
This skink chief first off costs more than you have him written down for. Secondly, his magic items exceed 50 points, which is not allowed. An enchanted shield costs 15 points, as army book over-rides the rulebook, while the ogre blade costs 40. That totals 55.
skink priest dispel scroll-85 pts
Dispel scrolls cost 25 points, meaning that the skink priest actually costs 90 points and you have him written down for the wrong point value.
In addition to your heroes being illegal, they are also sub-optimal skinks. If this is to be a tournament list against strong competition, then I recommend taking a scar-veteran rather than a skink chief.
core-
40 saurus warriors spears full cmd -510 pts
18 skinks full command 2 korxigor 1 cheif here-222 pts
18 skinks full command 2 kroxigor 1 cheif hee- 222 pts
I personally find 40 saurus too big and that skinks work better in units of 24 with 3 krox, but whatever floats your boat.
special-
14 temple guard full cm -275 pts
This is a weird number to use, as it doesn't grant full ranks. I recommend finding the points for 2 more and bumping the unit up to 16 (so when the slann joins it you can use the unit in a 5x4 formation rather than a 5x3 with 3 lonely temple guard hanging off the back or a 6x3 where the slann can be attacked if you are rear-charged. In fact, I would make this unit generally larger by dropping a few spear saurus and using the points to buy temple guard instead.
6 chameleons-72 pts
No rare choices? I think you will sorely miss salamanders in this army. Also, though this is less of a big deal, I think the list should include some nice and cheap skirmishing skinks. I'd change the core setup to two decent-sized units of saurus (20 works if that's all the models you own), a unit of 24 skinks with 3 kroxigors, and then some skirmishers.
