With Dilan by their side, it was fine to fight a little bit more aggressively than they would usually do.
Ailee and Oliver definitely felt Dilan's influence right off the bat, even more so when their courage increased thanks to the passive effect the title [Beyond the Stars] had.
Feeling more courageous, Ailee was able to use her abilities much smoother than usual, while the same could be said about her movements.
As for Oliver, he became more eager to use tactics in order to defeat his opponents instead of relying on his abilities and a high mana consumption.
For weaker opponents, it was not necessary to waste his precious mana. They fought Silver Tier-1 monsters with average stats of around 40 Units in a team of two, while Dilan observed them.
He finished off the monsters lurking around them, so as to prevent them from interfering in their battle, and observed everything else.
