You could probably word it a little different. Call it 'Tunnel Vision' or something, say he gets too focused on combat to notice traps or the like? You're allowed some leeway after all

Well, he does understand some traps (Sawblades, Spikes, Flaming Dart Shooters, Pits of Lava) but other than that he doesn't understand. He doesn't get too focused on combat to miss the traps he knows about since he's had to deal with them for almost a year every time he goes into the dungeon. Since some traps exist in other games that do not in the Dungeon, he does not know how they work and is vulnerable to them.
