Lemme toss a few thoughts your way ...
A Slann in 1200 points. Whoa. With no points left for upgrades, not a lot I can suggest. What lore are you running? I'd pick something blast-y myself, as you don't have a ton of units to buff up.
Saurus Warriors - 305
- 25 Saurus Warriors
- Spawn Leader
- Musician
- Standard Bearer
Bring them up to 26, so the Slann makes them an even 30 if he joins. Not that he has to, but ranks will work out when he does.
Skink Skirmishers - 115
- 15 Skink Skirmishers
- Patrol Leader
Drop the leader, add 5 skinks and split them into 2x 10. You're using blowpipes, right?
Chameleon Skinks - 140
- 10 Chameleon Skinks
- Stalker
Drop the stalker, split into 2x 5. I can't guarantee you'll have that many soft targets for them @ 1200, but two units should be able to handle whatever they need to, plus having the flexibility to handle different threats / split enemy focus.
Kroxigor - 260
- 5 Kroxigor
- Kroxigor Ancient
Yea for Krox! Drop the ancient + 1 krox and you should be able to afford the above changes, with some extra points leftover. I'd keep them over three if you can, you want some attaks to counteract WS3 derp.
Salamander Hunting Pack - 80
Do these still have extra handler options? If you have extra points from the above I'd pick up some handlers, and then dump the extra points into ... moar skirmishers? Or camo dudes? Depends on how much is left after all this.
