The first battle he had with the wolf there is no magic (mob rank name/rank, status display, ice magic, dimension magic). He only use a sword and the ??? skill +1.00 confusion. He discovered status,skill/magic, level up system afterwards and battle some monsters along the way out. The poison debuff he gets is from poison frog and not the wolf from the beginning. There's no mentioning about his little sister too if I remember it correctly. He met the party and the girl heal/cure him but the skill ??? didn't active so his current confusion is 1.00. He reached the city after that. This is what is happening in the web novel. I'm guessing the 2nd ??? confusion on the manga is to leave a deep impression on the girl for possible future heroine I guess.
