Grok in Heroes 5

Hero's movement points are increased by 5% instantly and by + 1% per every four level. The cost of Teleport spell is reduced by half.

Grok’s promotion as the Sovereign's "go-fer" was due to two things: his innate indefatigability and the Sovereign’s love for massacre. He is his master’s bloody entertainments manager, driving all manner of game and beings before Kha-Beleth to be slaughtered. The Sovereign knows that if there is a matter that must be handled quickly, there is no better fiend for it than the slavishly obedient and mindlessly brutal Grok.
