The Hundred Line Last Defense Academy Exploration

The exploration phase in The Hundred Line: Last Defense Academy is a mix of excitement and tension, as each decision can drastically change the fate of your party. These events aren’t just random encounters; they shape your resource haul and the survival of your characters. Picking the right choices means swinging the odds in your favor during this unpredictable minigame.

If you encounter any rare outcomes or alternate results not covered here, it’s worth discussing them with other players to fill out the full picture of what exploration can throw at you.

During exploration, you receive movement cards that guide your progress across a board game-style map. The map features six types of event spaces that regularly come up:

• BP (coin icon)
• Plants (leaves icon)
• Textiles (cloth icon)
• Minerals (rock icon)
• Machines (gear icon)
• Random (? icon)

The first five types reliably give you the corresponding resource, but the random spots can swing in any direction — sometimes delivering rewards, other times penalties.

Each event forces you into a choice that can lead to a definitive result or a chance-based outcome. Some choices are safer than others, but the real challenge is weighing risk against reward.

The individual probabilities aren’t listed in-game, but you can often infer your odds by evaluating the wording and difficulty in the event description. If it sounds risky, it usually is.

Unfortunately I can’t actually find out the chance of getting each outcome, but you can usually tell based on the wording and the difficulty of the space if your chances for a good outcome are smaller than for the bad outcome.

Here’s an outline of each possible event outcome, giving you the tools to decide effectively when exploring.

When an outcome lists options separated by “/”, it means either outcome can occur when you choose that option.

For example, “Random -2 HP” means a party member will lose 2 HP at random, while “All +1 HP” means every party member gains one HP. “Move +1” advances your position by a square, and “Textiles Chance +10%” boosts the amount of Textiles earned at the exploration’s end.

“Move Card +1” buffs your current move card for an extra step and it remains usable later. “Reroll Map” means the current map layout is shuffled, affecting subsequent moves.

Responses marked with “?” represent outcomes yet untested. Sharing your discoveries in these cases helps complete the collective understanding of the event system.

Outcomes with “?” as the response are the ones I haven’t tried out yet. If you try them out, please share what the outcome was so we can all get a more complete guide. Thanks!
