it does have phlegma (phlegm), haima (blood) and addersgall (gall bile). as the design stands i'd rather the four addersgall spenders (tauro/ixo/druo/kerachole) had been named after the four humours but it is what it is. but yeh its probably best not to look into skill names too much outside of 'it sounds cool' or you find out stuff like 'zwerchau is a longsword technique'
