Well, my speculation is for Kursus. I'm guessing this:

Spoiler Alert!

Sonic Leap Special Attack
On his turn instead of his normal move, Kursus may Sonic Leap. Sonic Leap has a move of 4. When counting spaces for Kursus's Sonic Leap, ignore obstacles. Kursus may leap over water without stopping, pass over figures without being engaged, and leap over obstacles such as ruins. Kursus may not leap more than 12 levels up or down in a single leap. When Kursus ends his Sonic Leap movement roll 3 dice once for all figures within 2 spaces of Kursus. Each figure rolls defense dice separately. Kursus and destructible objects are not affected by sonic leap Special attack.

Why so I think this?The playtesting thread told this.
With uncanny speed he bounds across the hilly land, leaping above the heads of his enemies. He halts, only for a moment, atop a hill; lets lose a feral roar, then leaps, his armored fists humming, into the swarming midst of his enemy. On impact, a sonic wave sweeps outwards, enemy troops stumble and fall; Kursus is the only one who remains standing. Here ends my speculation.
