It seems you’re referencing a specific, evocative phrase or title: (a dungeon-crawler JRPG by Nippon Ichi Software), combined with "RAR portable" — likely meaning a compressed archive (.rar) for a portable version of the game (e.g., for a flash drive, modded handheld, or Steam Deck).
Refrain, on the other hand, speaks to the repetition and rhythm that are inherent to music and poetry. A refrain is a repeated line or phrase, often used to emphasize a particular theme or emotion.
