Allegiance: Seraphon - Constellation: Thunder Lizard Engine of the Gods (260) - Artefact: Cloak of Feathers Skink Priest (70) - General - Command Trait: Master of Star Rituals - Artefact: Fusil of Conflaguration Stegadon with Skink Chief (250) - Weapon: Skystreak Bow ^also prime warbeast Stegadon (240) - Weapon: Skystreak Bow Stegadon (240) - Weapon: Skystreak Bow Stegadon (240) - Weapon: Skystreak Bow 3 x Kroxigor (140) Bastiladon (220) - Weapon: Solar Engine Thunderquake Temple-host (150) Celestial Stampede (140) Extra Command Point (50) Total: 2000 / 2000 Extra Command Points: 3 Allies: 0 / 400 Wounds: 78 So engine/steg/steg/krox in TQ and chief/steg/basti in the Stampede leaves you 120 points. I thought the Thunderlizards Skink Priest would go well here to take advantage of free CP use and give space for the extra artifacts we get. Steg chief can't get one sad face. Other option is a couple of skink screens.
Its obviously a very particular style of list. Low drop definitely helps a behemoth focused list control the flow of turns a little bit more, but im personally a fan of dipping into shadowstrike as a second battalion just cause you at least get some skink bodies in there. I think this list will be great into some matchups and a lot of fun, just suffer from the same thing all steg spam lists do... difficulty holding objectives.
You can drop priest and go for 2 drops. I like double prime warbeast idea. But you will have to drop priest and have no slot for additional artefact.
