Mac made it through several floors of the dungeon by biding his time and being resourceful with the items he found. He managed to take down about seven weaker enemies, including Seel, Omanyte, and Tentacool.
On the next floor, he was placed moderately far from a Tentacool. Mac knew the drill- take him down fast. He was unable to take hits, so he had to deal them. That's just what he did: from far away, he performed a very quick attack, dealing damage before retreating back. However, Tentacool followed him, infuriated. "You dare fight us? And with no advantage? You sicken me!" Mac could deal one more hit and take it out. To prepare for that hit, he dodged side to side as he leered at him. However, his evasive action proved unfruitful, as the Tentacool managed to shoot a stinger into his torso, poisoning him. Mac felt great pain, his claws sticking out further as he felt his hatred for Seviper fueling him. This was his opportunity: this chance allotted Mac to slash at the Tentacool (Night Slash). He knew he made a great hit: the poison fueling his attack, the Choice Band strengthening him, his opponent weakened by the Leer and Quick Attack, and the immense critical damage from the Night Slash. Tentacool fainted.
The damage left Mac weakened. He was at a very strong level currently, which was the best time to keep moving forward. He did, wincing from the poison. Tracks left in the water prompted Mac to run after them. They were mangled together, as if several Pokemon had walked that route. At a split in the path, Mac stopped. To his right, a room with a crushed wall and marks of battle, as well as the stairs. To his left, a room with several goods, including Oran Berries, Poke Dollars, and more. But that could wait. Mac went right, towards the stairs.
