ELDEN RING SHADOW OF THE ERDTREE DLC Putrescent Knight Bow Only No Hit/No damage Solo No summons

The fight against Putrescent Knight using only bow. This felt a very overwhelming boss at the start, specially that combo attack with the horse, but at the moment you understand that all its attacks have some delay and how to consistently evade the combo it became much more manageable.
(For me was roll forward, shot, roll to the horse, roll forward, then wait for horse to charge, roll to it and quickly roll forward)
The second phase is fun to do with jumps and let me put some arrows inbetween. With some more practice I probably could had been more aggresive, but I feared messing up.
And the phase transition brings the best attack opening for bow when you get it, which is mostly 3 jumps forward.
Also really liked the design of this thing, such a strange and weird horror monster. I love it!
A very solid boss overall, will need to check what is the lore of this thing with descriptions.
