This is not how degrades work. Also, it's besides the point, but while actually bursting/barraging the lobsters, they are not attacking you. And to OP, the reason farseer kiteshield is not often discussed or bought is because arcane spirit shield is clearly better, and not too expensive(50m or so?), as opposed to the elysian/divine which are better than the cks(but very expensive), and the eek compared to the spectral(eek is better).
