300pt Restriced.
Adv Sentinel on 150 setting
Vet Shadow Lass with Ambush
Vet Valkyre Thunderbolted to Defenders

Bam the Ladies follow the sent around lending him an 18 defense through Shadowlass' Defend. if anyone decides to come deal with the girls they gotta get through the sentinels 10 range and finally each of the girls has a 6 range..I know it's no where near perfect but it's been alot of fun in play testing

awesome! mine must be a misprint, shes marked as an Avenger but the website does show her as a Defender. Oh man...I should fill up those points with some pogs..a 2 and a 3 pointer just to stand in front of the girls for some added protection

Or lucky break on Valkeryie, just in case you want that Blades roll that was a 1 to turn into a 6 (Possibly)!

Lucky Break specifies you may only reroll dice used in an attack roll, so no BCF rerolls for you!

Im not sure, but does defend work for the sentinels?

That quote is from the original Sentinel rules, so the Advanced Sentinel rules from the DoFP set might be different. However, Defend is not mentioned, so it should be possible.

You're good to go with the shared defense.

Even with it, I think the low level Sentinel goes down like a bag of hammers. At least, that's what I've seen happen. Be sure to let us know how this team does!
