In games where "leveling up" both involves sudden jumps in ability and isn't simply a training montage back in town, I tend to roleplay it as a moment of sudden clarity. I have never trained at combat or magic use, but, in those things I have attempted to master, there have occasionally been moments when it "clicked" and suddenly everything made sense, leaving me far better equipped to face the subject afterwards. Admittedly, these moments tended to be triggered by studying rather than by killing a set number of goblins, but the principle is the same.
