For fucks sake, some of these Shattered Connection EX maps are bullshit. Intangible Sigh I EX is my current source of frustration, because stepping on the completely normal node to the left of Rubble I Type 1 dramatically increases the alert range of one of the super ELID bosses. And I must emphasize, there's absolutely zero indication this is going to happen before you step there and fuck up the entire mission.
This isn't a puzzle, it's random bullshit and terrible game design.
No, I don't want someone to immediately link me a guide. I want to vent my goddammed frustration, not have my hand held through the level.
Edit: And of course you can't check the initial alert range of the giant ELID's before starting the level, because god forbid the game let me plan a strategy before spending resources.
