The wolves were genuinely terrifying for Ning. Unlike the other beasts he had fought until now, they were fast and did a lot of damage.
Each time he battled a wolf, he had to make sure there weren't any others around. The only time he possibly had an easier time was when the cards he pulled out were Uncommon or higher.
Otherwise, each fight with the wolves felt like a battle to death.
Of course, that was what you got when you went into a level 50 dungeon as a level 35 and started fighting wolves that were between levels 40 and 45.
Each wolf was almost as strong as he was without any equipment. So, he had to be extra careful when he fought.
The dungeon was a massive cave with many different routes and was no better than the maze from the Vileshroom dungeon. In fact, this might even be worse as there were simply too many routes that led to nowhere instead of immediately stopping at a dead end.
