This mod should be Nether-aware.

[Deathwing777]

Hi, I ran into an issue when using this mod in conjunction with Hybrid Dog's Nether mod. The Shadow Realm 1 HP/sec when below y=-200 makes the Nether completely unplayable and traps players in an endless death cycle with no hope of escape. I have added a global table NETHER with a function NETHER["is_player_in_nether"](player) to the Nether mod, and a simple test in the Shadow Realms realm.lua script disables the 1 HP/sec. For completeness, I added a check for the NETHER global table, and use the result of that to instantiate a local function which will either just return false (if no nether mod is installed) or call the nether mod function to test player state. I also added "nether" to optional_depends in the Shadow Realm mod.conf.

It would be nice to have some configurable options (possibly via fmod), so we could change the y level at which the 1 HP/sec damage starts to happen. I may do that next, and kick it back up to you.
