[No Speed] Terror either doesn't move or moves so slowly that players can outrun it easily without items.
[Low Speed] Terrors are slow but you need an item like Regen/Glow Coil.
[Medium Speed] Terrors have average speed and you need at least Speed Coil.
[High Speed] Terror is fast and you need stronger coils like Glass, Delicate or even Emerald.
[Extreme Speed] Terror is so fast that you are unable to outrun them - only delay your doom.
