i'd say currently the biggest draw in this game is by far building, followed by exploring. progression through fighting bosses is primarily how to advance (most of the current game can be completed without fighting a single boss, even if it is difficult to do so). if your noncombatants like to be creative and build, then go for it! also bear in mind the game is maybe 3/5 finished. more content will be coming, which will likely expand all aspects of the game, from areas to explore, monsters to fight, to items to craft and things to build.
