Hi there, i’m looking for advice, just want to create a 500pt vader’s list.

what do you suggest?

This isnt by any means a good list but it is easy enough to put together with what most people will have. Vader uses a lot of your points in skirmish so its tough to get in multiple other threats. The shores and sniper give you some early range and then you have the Snows for an advancing threat with Vader. Keep them in cover and use 'New Ways to Motivate Them' to get them into Flamer range quickly to eliminate a unit. Its a old play but fun when it comes off. Can even throw Recon Intel on the Snows to help. Naked Stormys arent great but I find you need at least 6 activations in Skirmish. Keep them alive rather than shoot and position them for the mission objectives. Fear along with Master of Evil can be nasty on a skirmish board, especially when units cluster in the middle.

496/500

Darth Vader (190 + 18 = 208)
--Force Push (10), Saber Throw (5), Fear (3)

Shoretroopers (52 + 32 = 84)
--T-21B Trooper (32)

Snowtroopers (48 + 20 = 68)
--Flametrooper (20)

Stormtroopers (44 + 0 = 44)

Stormtroopers (44 + 0 = 44)

Scout Troopers (Strike Team) (20 + 28 = 48)
--DLT-19x Sniper (28)

Alternatively a crazy Imperial charge list for 499. Relies on opponent not knowing what to shoot first and having decent cover.

Darth Vader (190 + 13 = 203)
--Force Push (10), Fear (3)

Snowtroopers (48 + 20 = 68)
--Flametrooper (20)

Snowtroopers (48 + 20 = 68)
--Flametrooper (20)

Imperial Royal Guards (75 + 25 = 100)
--Electrostaff Guard (25)

Scout Troopers (60 + 0 = 60)

Honestly I think if you are ever going to consider taking Fear and you have 2 points spare you should always take Force choke, dealing a free damage is so much better than giving out 1 extra suppression a turn, particularly as choking out a heavy from a trooper squad can significantly reduce their damage output.

I've done pretty well with this list.

Darth Vader (190 + 10 = 200)
--Force Push (10)

Stormtroopers (44 + 9 = 53)
--R4 Astromech Droid (9)

Stormtroopers (44 + 19 = 63)
--FX-9 Medical Droid (19)

TX-225 GAVw Occupier Combat Assault Tank (155 + 28 = 183)
--Imperial Hammers Elite Armor Pilot (10), DLT-19 Rifle Pintle (18)

Commands:
Implacable (1), Vaders Might (1), Pinned Down (2), Fear and Dead Men (2), Master of Evil (3), Darkness Descends (3), Standing Orders (4)
