1. Never Get Tired
Command: plr_tired_mode_entering_percentage
Value: -100 (any number as long as it's negative).
With this little command, even if your stamina reaches 0, you won't go into the tired animation. This means that you'll be able to continue running even with 0 stamina. You'll still need the required stamina to perform special attacks. This cheat is useful for running away after accidentally running out of stamina near an attacking boss or monster.
2. Matrix Effect
Command: phys_timescale
Value: 0 to how much your pc can handle.
example: phys_timescale 0.1
If you're a fan of martial arts and the Matrix or that Jet Li movie called The One, you'll recognize this particular visual effect. In essence, it's a time scale intended for objects and not the entire world. You and the monsters will still move around normally (or with how you set your host time scale), but objects will break, crumble, get obliterated in awesome slow motion goodness! Also, when you kill monsters, they will die in slow motion as well as you continue fighting normally with the others! Imagine insane battle scenes where pillars crumble in epic slow motion as bodies of monsters you fatally wounded slowly die in the air or tumble away as you continue your rampage all over the place!
