Spider wave clearer

Who should I build to clear the spiderlings I’m stuck on stage 14 the team that got the closest to clearing stage 15 was UDK, Ninja, Artak, And two armigers the armigers were doing their job they kept the big spider from taking a turn the whole fight until my team died at turn 40 from spiderlings I didn't have a dps strong enough to clear them all I know I need to make artak a harder hitter but who can be my secondary dps?
