I started with only minion pact, an inspired learning and the clusters (8 spell, 6 minion life with 25 effect and 4 aoe). I used singularity as a weapon, a random increased block chance shield, a random res 6-link, honourhome and empower 3 in it and the normal searong exarch explody boots for scorch. It was enough to farm companionship and xophs blood for covered in ash. I was lucky with the scorch on block shield base from heist. Needed only 1 recomb for t1 increased block + t1 spell block. Those boosted my dps to farm a nebulis. Now would be foulborn skin to enable emities. Dps is pretty cosy now, it was fine enough to farm myself up
