As I commented before, killing Jim was huge. It's just like killing a president nowadays. Jim's ability didn't focus on himself and his physical strength, but in the creations and things around him. In an actual 1 vs 1, even a 18 year old vampire can defeat the ex-vampire lord with ease. Without him it is unknown if the Dalki possess the knowledge to create more vampires. It is highly unlikely that they would want to, but some more intelligent Dalki like Graham could try. In addition, there won't be an unlimited amount of six-spiked Dalki, even if it's for a short period. For the leveling up, I had two theories. The progression from vampire to vampire noble was 10 levels. The progression from vampire noble to vampire lord is 20 levels. The next one could either progress 30 or 40 levels. If he doesn't get an evolution or anything from level 70, then the next one might be level 80.
So... no evolution at level 70... that is quite disappointing as that means we are not going to see it for at least 10 more levels, if not 20 or 30. Considering how long it takes to go up 1 level, unless the next evolution is not level dependent and has some other trigger mechanism, this story may drag for a while with Quinn too weak to do much and no real way to increase his strength. He gets no bonus for killing 4 spike Dalki, and isn't strong enough to fight 5 or 6 spike Dalki. Hopefully Bliss showing up and Mona having a map to Richard's special place, we can get some information and push the story along.
So no body has realised yet that Blood crystals and the weapons made from them tend to have the owners ability as well. If that was Jim then Quinn will be able to get the equivalent exchange ability or who knows maybe an upgrade in the system will happen. Bliss shows up now, I don't think Quinn will trust her after all showing up but not helping at all. It would be Eno all over trying to manipulate things in the shadows which Quinn doesn't take kindly to more so with the loses they suffered. Hopefully the Dalki can't use the demon tier without Jim and his ability but Graham is still around. Just hope that whatever technological skills he has are under Jim's and not enough to finish the job.
