Trophy: Echoes of Jealousy 
In the next area, you will have another boss fight. During this fight, the boss will occasionally spawn puppets that slowly walk towards you. If they get caught in a fire attack, they will catch alight and rush at you, exploding. For this trophy, you will need to complete the fight without taking damage from any of these puppets. The best way to deal with them is to immediately attack them when they spawn while they’re still slow. They will die in 1-2 swipes, and you can then also Soul Siphon them with 
to charge your ability. If you see the boss charging a fire attack, stay away from any puppets to avoid them becoming explosive. If they do get by fire, stop attacking and let your stamina recharge, then dodge when they rush at you.
Next Area: Ebisugaoka Fifth Visit
Gekidami says
I didn’t get hit by a fire puppet attack, but still didn’t get the trophy. I reckon any attack from a puppet will void it. One whacked me in the back.
Newbie says
I don’t know if “occasionally” is the right word for how often the boss spawns mobs. I don’t even have time to kill one before another one attacks me from the back. And the long walk you have to do after you restart is just aweful. Yes I’m bitter.
Henry says
You’ve probably done it by now, but for others seeing this I just let myself get killed by her if I mess up and it loads you at the beginning of the fight. So you don’t have to sit through that long walk
I popped the trophy after a few tries of doing this
