Here's the story: your walking around, and you find a secret base. Little did you know, the base is littered with traps. As soon as you enter the front door, you trigger a tripwire and get shot with arrows, unphased but low on health, you trudge on. But, at the end of the hallway, you spot a chest... you open it, and the next thing you know, the floor opens up and you fall to your death.
Untrollable is a simple texture pack suggested to me by a Player8, a commenter on my Invisible Trip Wires texture pack. This pack not only makes trip wires bright red, it also makes trapped chest much more noticable.
Trap chests compared to regular chests.
TNT trap thwarted by the bright red texture of the trip wire.
Download and install, and add to global resources so when you join servers, you can still have the texture pack, but no one will know....
