I do agree with the first suggestion. What more, even though I do play ghost, I did not even know that such was a thing. It was probably not intended. The seconds on is fine as well, and I completely agree with you. However, I do not think the cost of Blood Spike should be increased, as it would leave the skill completely overshadowed by twister. Twister offers far more utility for the cost of just 2% more HP, despite the range - one you get only after going dangerously low on HP anyhow. Likewise, the argument that it needs to be nerfed just because River Sword exists is completely insane.

As others have mentioned, the main benefit of picking Blood Spike over Twister is the additional damage. Twister offers a huge amount of utility with the pull it provides, but has less universally applicable 'optimal times to use'. Often, people who aren't using cinders won't even take Scarlet Twister because of the SP investment.

Making Blood Spike hurt the caster a bit more than it already does should (hopefully) shunt the ability from "use this every single turn unless your opponent is full anti-magic" to an actual decision about resistance spreads, number of targets hit, and current health. I can't imagine the aforementioned change would ever dissuade a Ghost from using this skill as often as possible when two or more enemies are able to be hit simultaneously, but the intent was to trim small bits of power, and not chop the legs out from under the class.
