Sure thing, It's pretty easy.
Base coated with Vallejo Heavy Charcoal
Lightly Dry brushed all areas to have lightning arcs running over with GW
Lightly squiggled on lightning arc pattern with GW
Wash with Secret Weapon Black Red
Layer over select spots of the lightning arcs with GW
Evil Sunz Scarlet
Wash again with Secret weapon Red black
Evil Sunz Scarlet as an extreme highlight over the first layer
At this point I'd assess it and make a call on whether a third pass with the wash and layer is necessary.
Dry brush edges with GW
troll Slayer Orange
Dry brush blade tip edge with GW
Clean up any messy Dry brushing with spot washes of Secret Weapon Black Red
Last I did the bead on the power sword with a base of GW
Khorne Red, layer Evil Sunz Scarlet, highlight with Troll Slayer Orange, extreme highlight with Yriel Yellow.
Then spot wash the bead with Secret weapon yellow sun, once dried wash again with Secrect weapon sunshine, then painted highlight to the lightning acrs where they meet the bead with GW
Yriel yellow and finally spot wash both the bead and the yellow highlights I just painted with Secret Weapon Orange.
Then a gloss varnish on the blade.
I use a few different brands and you could likely achieve similar results with just the citadel line but I think the Base coat of Vallejo Heavy Charcoal is a must use.... and I probably wouldn't use anything other than the Secret Weapon black red wash too but there may be something comparable to that in Citadel's wash line.
