That is from an older patch, it's no longer like that and as you can see even the runeword is not made by socketing a Tal + Kab stone anymore, it's now an Enhanced Runeword, very similar but not the same. Also Qarak's % damage to Bloodlust was nerfed some time ago, so it's just up to 100% now on both. And i don't get what the title has to do with what you are asking.
