OK first of you NEED RANGE.... ( Bow, Throwing Axe, Spells, Ect. )
1. go to MC
2. get past the first 2 molten giants by going through the wall to the right of them.. ( you should be walking over lava "hence the zero gravity" )
3. get high enough to walk over the mobs..
4. attack a core hound ( might have to slowly go down, to get in range )
5. when you finaly get agro, teleport to "Core Hound" location
6. dont move just use a range weapon or spell
7. when it dies teleport to "Loot" location to get the loot without atracting unwanted agro..
you can do this with any mob in mc that does not have ranged attacks..
Core Hound, 409, -661.207, 1136.619, -101.571
and this is where you go without atracting adds..
Loot, 409, -672.616, 1132.853, -125.331
