What is the best way to get more hero experience from the hero exploration in Whiteout Survival?

Equip your heroes with experience-boosting gear before sending them on explorations. This can significantly increase the experience gained from each mission.

Focus on sending heroes on longer expeditions. They take more time but yield significantly more experience. Plus, it's more efficient in the long run.

Pair up heroes with complementary skills. They tend to perform better, thus earning more experience collectively.
