Shoutout to Yabberdabberdoo for some of the strats (notably the prison skip, the Delavar's Lair routing and the final boss positionning).

It is important to know that the overhead attack (triangle) does more damage (around x1.5 - x2 ?) than the lateral attack. Most of the time you can also use charged attacks to go faster and if you fail your attack you can press R1 twice to skip the stun frames. This whole fighting strat saves a lot of time.

For the sewer rat you can repetitively do : normal attack which he blocks, 2-tick charged attack, block, etc. For the prison guard you can alternate between a normal overhead attack and a 2-tick charged attack. For the gargoyle, you can step back, charge an attack and wait for them to come at you to deliver a powerful strike. As it is dangerous to just try to stunlock them because they sometimes attack faster, it is both safer and faster to do that.

In the Fabian Central you can skip the whole shadow spell and just block the fireballs in the corridor.

This WR is still beatable, you can save some time on menuing, not running into walls and some fights in which I had a bad RNG. The skillcap is not very high though, most of the speedrun depends on your knowledge of the routes and not forgetting important items.
