Lukas the Trickerster is the Bloodclaw upgrade. For 140 points you upgrade one Bloodclaw to this guy. He, and everyone with him cannot use a Leadership of higher than 8. In exchange you get WS and BS 5, a Wolf Claw and his special rules. Doppleganger Cloak, all hits directed at him must be rerolled. and The Last Laugh, he has a temporal bomb wired in place of his second heart, if his primary stop beating the bomb goes off and freezes him and the one who killed him in a stasis field. In game play terms, if you kill him in close combat, when he is removed from play, him and every model in base to base contact with him are removed from play.
Njal is still the most kick butt of all of them tho.
The models are vrey cool. I will be buying the Wolf Gaurd box with the Termie Wolves. Im curious to see if Bjorn the Fel-handed is going to get another model. Njal is a must have, and now I have a reason to buy Logan Grimnar.
This codex and all the art work is great. Pitch perfect for the Wolves, and it should make any future Space Marines excited about the possiblity of a release for thier Chapter. Sort of scares me tho, because rumor says that the Tyranids are next.
