Levels VS MonsterBlocks

Followed shortly thereafter by his Levels module, which gives spatial distance relative to elevation represented in 2D via token vision.

TheRipper93's Levels module. This lets you overlay parts of the map to add depth or even just to handle height more easily. This is both a visual effect and a mechanical one as it adjust the player's elevation as needed.

I'm working on a map right now and I'm using the Levels module (found here: https://github.com/theripper93/Levels). It's been great so far, but after setting everything up I noticed that when players deselect their token they can see all the levels above them for a split second (but not the tokens on them) except for the tiles they're beneath. Hopefully the video below will make up for my bad explanation.

If you are using FoundryVTT I recommend using Levels (https://github.com/theripper93/Levels) for this map.

I seem to completely have misspoke. I meant to say the Levels module: https://github.com/theripper93/Levels. I'm wanting to know if someone casts Hunger of Hadar on the third floor of a tower at 30ft of elevation if the terrain drawn out will affect players on the first and second levels.

that's probably because you are setting it up wrong - be sure to read the documentation (it's kinda crap) or come into my discord if you have issues https://github.com/theripper93/Levels

If accessing the monster actions is the problem you might try the Argon HUD or change the default sheet layout to something like the dndbeyond character sheet module or monster blocks so it's more familiar
