Out of all monsters in the undead army, the ice trolls were the fastest, aside from the flying ones. Feiria only sent those to harass the human side. Still, Sigma didn't have a hard time stopping them… she probably knew that Sigma would do the same with her flying monsters thanks to his crazy attack range, which was why she didn't send them.
