I found it easier using fine bombs with darkwar4ever's Vindictus+ revision 1 .hfs files.
Instead of throwing spears, I made it throw a small bomb instead which hits the entire region.
I had a problem with spears because once I throw the spear, blood lord disappears and attacks behind me and stuff.
It ruined the entire macro, so I changed it to bombs instead which instantly kill all mobs in the entire region.
