First off i would like to say that would make an awesome Metal Band - Lemartes and the Death Company
Pros & Cons of Lemartes
I'm slowly realizing that he might be a better choice for my chaplain of the death co. The up sides of him is that he has Feel no pain where a normal Chaplain doesn't. We all know that when you take enough wounds you have to put it on your Chaplain and you can make all the saves but on him, its rather disappointing. And one of the biggest pros for Lemartes is the Fury Unbound. If he takes a wound he jumps up to S5 with 5 attacks. After that on the Charge thats 6 attacks at S6 re-rolling hit and wounds. All of that for a small 50 extra points. And another big pro is he doesn't take up a Elite slot!
The Cons, he only has a few but it might be tempting not to use him. The jump pack he has is kinda annoying. We all know that a death co with jump packs are a waste of points. a 20pt awesome model jumps up to 35pt. A 10 man squad is an extra 150pt for jump packs. I don't think its worth it and for another 50pt you can have a storm raven. So Lemartes with a JP with a squad that doesn't, can't go into a Land Raider or a Rhino, it forces you into a Storm Raven (if you have one built) or your foot slogging it. I have yet to foot slog my Death Co. but i know that is just asking for everything to shoot at them. A Bolt Pistol, thats all he's got. where a Chaplain you can give him better weapons.
Now the Elite Choice Chaplain is nice to have if you want a little more protection for your Death Hammer unit. you can put him and his boys in a Land Raider or a Rhino. He can take a plasma pistol or a a bunch of other weapons. Or if you want make him a terminator for that 2+/4+ save. He's also a IC so if you want him to break off and kick another units ass he can. I don't know why you want too, unless your fighting IG and you are surrounded by plasma/melta troops and as soon as you kill one unit another one just blasts the SH** out of you. And lastly, a chaplain is 50pt less! That can make the difference, its a attack bike with a Multi-melta!
They are both a must for your death company. I'll play him on friday (my game club) and let you know the outcome. If anyone has anything else to say about this matter feel free.
