I'm curious in how weak my Chikage is? Its got 560 AR in blood mode and 370 AR standard. 40 BT and 30 SKL.
The AR rating in the stats screen is misleading for the Chikage, the first attack after the transformation (it needs to be immediately while transforming) easily does double that, it's very fast & does absurd damage but requires good timing. You also need good Blood Gems to get the most out of your weapon.
Another thing is that the "Lost" version of the Chikage has a circular blood gem slot, which is great because you can find +32% Blood Attack blood gems, the highest you can get on other slots is 27% , which is a huge difference.
