And I am done with the second floor of the defiled chalice and the watchdog boss.
Took me a couple of attempts (way WAY less than chalice ebrietas lol like maybe 5 attempts?) but I figured out a good strategy for myself in the end.
My first attempt, I just used a regular saw cleaver but the damage and the way it attacks just didn't have the reach or damage I wanted. I got it to maybe halfway down its HP bar before I got one shot KO'd by that flaming charge attack. I was dumb for sticking a bit too close and not noticing the signs that it was about to do that attack.
Next few attempts I switched to Ludwig's blade's second form (the standard side slash attack had good reach for me as opposed to the saw cleaver's second form's downward slash). Died on those attempts either from being one shot KO'd or getting locked into one of its attacks and then wailed on.
My last attempt a few moments ago where I did win, I went in with a plan. The only safe time that I could attack it, especially with the blade's slow attack time, was when the boss used a downward or straight forward bite attack when I was maybe a medium range distance away.
When it did that attack, I could rush in and whack once on its head and then dodge back to safety while continuing to circle each other.
The upward bite attack it has, to me, seemed to have a very short recovery time for the boss the start its next attack. At the same time, when it does the downward bite attack, it was a bad idea to immediately rush in to try and attack it. This was because I figured out the hard way in a previous attempt that if I ran in too soon after it did one attack, it could immediately start a chain of more bite attacks. It was hard for me at least to dodge back when it did that (I'm sure there are plenty of people who could dodge back out) but it seemed way too risky for me. Especially since it only took maybe 2-3 normal attacks from it to kill me.
The fire attacks it used like the one where it coughs out fire puffs and when it uses its claws to make a fire wave were easy enough to dodge. Though in earlier attempts, I got stuck in one of those fire attacks and couldn't dodge out and it finished me off lol.
The attack where it spits up lava let me dish out 2-3 attacks before I had to back off. The fire explosion it does is pretty telling and easy to dodge. The fire charge was ok to dodge as long as I was a good distance away.
I had to switch to the charred hunter's outfit as well as use the increase all defense and increase fire defense runes.
My strategy was really slow and I had to be patient because every attack it did could immediately end me. But it felt to me very low risk how I did it and it worked out in the end and that's all that matters.
Man, I remember when I first fought this thing in an earlier chalice. I was way overleveled for it so I was just super aggressive with it and didn't care if it attacked me. This time around, nope, gotta take it slow lol.
