Hmmmmn. iirc, it was:
P3 Umbral Umber base
GW Tin Bitz all over
Shade by adding GW Orchide Shade to the Tin Bitz. Keep this semi-transparent. Shade as though for NMM (That is to say, divide the blade into top and bottom sections. Shade one right to left, and the other left to right)
Shade more by adding some black to the Orchide/Bitz mix. Take this all the way to pure black at the extremities.
start adding in GW Boltgun Metal to the Tin Bitz and highlight as if it was NMM (as per the shadey bit, but backwards)
Once you're onto pure BGMetal, add in some GW Mithril silver for the very edges, and for the tip of the blade.
Redo the junction of highlight and shade with thinned Tin Bitz, just to pop the colour up again.
Wash selectively with thinned GW Leviathan Purple (In fact, pretty much the whole mini has been liberally doused in Leviathan Purple. Works very well with green, yes it does.)
It probably took longer to read and process all that than it does to actually paint it. It's not that fiddly.
