Okay. After collecting my information and then some extra time when the site was down, I'm ready to continue with Season 3. A few notes before I begin though.
Season 3 improved on many things from the first two seasons for the temple runs. One of them is that unlocked doors only opened through the forward path. What I mean by this is that let's say that from the Pit of the Pendulum, the doors to the Chamber of the Sacred Markers and to the Tomb of the Headless Kings opens, but the Chamber would only force you down into the Tomb. Completing the Tomb's objective won't open the upward path, just the door to the Jester's Court.
Another thing, and this is one of the main reasons why I love Season 3 the most, is that almost no rooms had a simple 'press the button' objective, even the Pit room! This makes locating the temple guards much easier because in almost every room, ALL unlocked doors WILL open. (except for instances of the previous note, but it still helps A LOT)
Another thing with Season 3 is that it featured much fewer full on dead-ends. In fact, as far as I know, the costly detour in The Bifocal Monocle of One-Eyed Jack (the very first episode of Season 3) was the only dead-end they used in Season 3. They did still use detour rooms to waste time for players who entered the wrong rooms, but other than the first episode, they never had a path lead the players to a full on dead-end.
Some notes about temple guard locations:
First of all, as any Legends fan knows, no temple guards are ever hidden in the Jester's Court, so that makes locating the temple guards easier.
This note is specifically about the Ledges. In Seasons 1 and 2, if a temple guard was in the Cave of Sighs/Ledges, they would be at the bottom level, out of sight of the players. However, in Season 3, if a temple guard was in the Ledges, they would be at the top level, out of sight, and early in the season, the lights in the room would be dimmed to make sure the players were unable to see the guard. This idea of dimming the lights actually makes it kind of obvious when they were hiding a guard in the Ledges.
One last note about Season 3 involves the half-pendant locations. It seems that in Season 1, they hid the pendants way too harshly and they were almost never found. In Season 2, they weren't "hidden" very well and were almost inevitably found. Season 3 had a good compromise between the two. The pendants were still hidden in plain sight, but often in places where the players may not have noticed their presence.
Enough ramblings. Let's continue.
