Already platinumed. Also happens to be my very first platinum (on any platform ps3/360/ps4/xb1)
I almost never go for trophies, but in this case I already had almost every trophy by the end of the game anyways. I stumbled upon the having all the requirements for seeing all 3 endings, so i just did the save backup and load to quickly get all 3 of those ending trophies.
I then had 3 trophies left to do. all weapons, all tools, and the chalice boss one. The first two just took looking up what I was missing and quickly found what I needed (2 weapons, 1 tool). Took less than an hour.
Last one was quite a bit more painful since I never really touched the chalice stuff and so it took a good 5-6 hours to get it. Which was fine because once I finished the game I was still itching to play more. After going through some rather hellish chalice dungeons... that itch got scratched down to the bone. Almost gave up at that half-health dungeon. F*** that place. This trophy reminded my why I never normally go for trophies.
