Karl turned the group toward the rest of the Hill Giants, which were forming up for a charge on the humans now that Rae had blocked their boulder barrage. They weren't going to sit and wait for the humans to compile a full attack force like the last time they were here.
So, they charged, but so did Karl, which forced the end of the line to turn and face him instead of the pike line.
He could feel the power building in the air as he attacked, but Karl dismissed it as something that the Hill Giants were working on. If he could kill enough of them, the group spell would collapse, and that would be the end of it.
With [Haste] activated, Karl left the rest of the group behind, except for the Spider Golems, which accompanied him into the Hill Giant lines. The trio hacked limbs off the Ascended Giants and left them wounded as they headed for the Commanders.
