"This blade is bowed and black as the desert night. The hilt is inscribed with gold, calligraphic glyphs."
Dropped by Saad Amus The Sky-Bear or one of his clones, which can be found in the underground at random. Functions similarly to the Vibro Blade in that it ignores armor value, but it deals slightly higher damage and does not need to be charged with an energy cell to work. However it still can be disabled by EMP and has a short boot sequence.
It is very useful weapon for any character to have as it lets you dig through walls and doors with moderate time investment and makes dealing with high AV enemies much simpler.
This weapon is extremely valuable to anyone with moderate strength. It allows characters to perform decently in melee combat against almost any reasonable opponents with minimal investment.
Characters with extremely high strength, however, will prefer to carry an alternative sword for use against lightly-armored enemies, since the Vibrokhopesh's damage increment (while high) is not quite as high as the very top-tier materials, while its ability to equal the opponent's AV means that it can't hit a damage multiplier above x3.
