Wallace watched the fifth round where Vanessa struggled a lot to last 15 minutes against the automaton.
This time, one team loses a point as one of the participants was not able to last and left unconscious on the stage. He was a member of Maja's team and he wasn't used to fight a magician that could quick-cast while buffed by a three-layered movement speed spell.
The other four only lasted for so long because they have a very strong defense and sturdy Mana Shell.
The automaton seems to have reached its peak after this fifth round. It probably learned Vanessa's Motion Break, a technique where her cast was being delayed to catch the target off guard. It wasn't a magic spell but a skill for those who possess high level of control on Mana.
Vanessa had only learned this trick after getting a chance to dip in the Revitalization Mana Spring.
