Gorgons are obvious so long as you've done that part enough times. Hard mode makes their tracking slightly more sensitive, makes them more persistent towards something they heard, longer duration stationaries after being alerted - they look towards the direction of what alerted them for a longer duration before resuming their patrol path -, and the addition of 2(?) permanently static Gorgons (sorry, I don't take a left route much) so as to prevent folks from taking the most direct route possible in normal where you can simply sprint single-file to the exit cave. Jump puzzle: Simple basic method: ANY class can make it to the lower ledge from the 3rd platform that spawns with practice and good timing. Warlocks use focused burst or balanced glide (either work, but balanced is exclusive to sunsinger). Titans use either lift, just not catapult. Hunters use double-jump with bonus height (potentially even triple jump as GS, but personally never bothered trying it since I manage with double-jump as either subclass). Hunters have the most difficulty when using the 3rd platform and they must have a high agility, be sprinting prior to jumping off, jump in the direction of the ledge very near to them (there's a corner I like to use), and save the double-jump for very late so as not to smack off the wall and fall or die from the fall out-right. Second method: Involves using the cave to the left (if you're facing the appearing platforms) of the spawn location and although I only use this method with my hunter as a Bladedancer with its super ready, I've heard rumors that any class can take it since going into the cave activates the 2nd set of appearing platforms, but I'm not sure I'd like to try timing a landing on an appearing platform, lol. Anyways, as a Blade dancer with Arc Blade ready, look down out of the cave, you'll recognize the platform area that leads straight into the throneroom. That's your target and yes it's a huge drop. Activate arc-blade, sprint and jump (do NOT double-jump) out of the cave in the direction of the throne room hallway landing and spam your arc-blade swipes until you reach the far wall, then drop straight down. If your arc-blade can last until the landing (seen some pull this off with the exotic that reduces arc-blade energy consumption), you don't need to use the double-jump upon smacking the ground (seems like arc-blade prevents all fall damage), but if you're like me and lack that exotic, use that double-jump to stop your momentum before landing (not sure if it's a bug or what, but occasionally I've rushed this path and double-jumped at the beginning, resulting in a drop from one of the highest heights possible in the game, yet still survive. Even if you don't survive the drop, your ghost is there for a teammate to revive you (even on hard, since this part of the raid is similar to constructing the conflux to enter VoG).
