Can I do this?

Ok, my hunt for a new Inquisitor has begun

Can I field this?

Ordo Malleus Inquisitor
Terminator Armour
Daemonblade
Psycannon
Brain Mines
Psyker

I think I'm all good, but not too sure on the daemonblade, which I really do want to take?

Unfortunately you can't take termie armour and daemonblade. To take the daemonblade you have to trade either your bolt pistol or chainsword for it, but you need to trade both of those for termie armour.

That is a shame that the rules do not support this =][= built, but there is nothing stoping you from modelling this guy still

Thanks guys - I'll get down to work on him - I ran with psyker to drop the hammer for a force weapon.

Got the old RT Inquisitor Lord in T-armour, so I'm going to glue him and try and get him painted in the next few days

Awesome!!!! I like the resurgance of classic models that is happening on the forum these days! I can't wait to see how this project turns out.
