EXP
A dark currency of violence that trades a monster's life for the killer's growing power.
EXP stands for 'Execution Points,' a mysterious and ominous mechanic found within the underground world of Undertale. Unlike traditional role-playing games where experience points represent growth or learning, EXP in this universe is directly tied to violence and the act of ending lives. It serves as the primary metric for increasing a being's 'LV' (Level of Violence) when they choose the path of conflict rather than compassion. This system acts as a dark counterpoint to the game's core theme of mercy. While monsters can gain EXP and LV from killing other monsters—as seen with the Royal Guard and other monsters who possess LV in the game's lore—the protagonist holds the unique ability to reject this cycle entirely. The presence of EXP highlights the fundamental difference between the two species: for monsters, gaining power often means losing their humanity or soul, whereas the player character can choose to resolve conflicts without bloodshed.

Lore & Background
In the hidden depths of the Underground, EXP is not merely a number but a reflection of a soul's capacity for destruction. When a human kills a monster, they absorb the creature's essence in the form of Execution Points. This accumulation directly fuels the 'Level of Violence,' a stat that quantifies how much force the killer can wield against others. The system suggests that power in this world is not earned through training or study, but through the extinguishing of other lives. The existence of EXP creates a tragic irony for the monsters who inhabit the Underground. They are often desperate to escape their prison and believe that gaining strength is necessary for survival. However, the game reveals that true strength lies in the refusal to participate in this cycle. The mechanic serves as a constant temptation, urging the protagonist to become stronger by becoming more ruthless, effectively turning the player into a monster themselves if they choose to follow the path of violence. Notably, monsters can also gain EXP and LV from killing other monsters, as evidenced by characters like the Royal Guard who have LV in the game's lore.
In Their Own Story
The pixelated heart on the screen flickered red, pulsing with a rhythm that felt too much like a heartbeat. A small, blue frog-like creature stood trembling before you, its eyes wide with fear rather than aggression. The menu hovered in your mind: Fight, Act, Item, Mercy. You selected 'Fight,' and the world turned gray. As the final blow landed, a soft chime echoed through the silent cavern. +1 EXP. The number on the side of your screen ticked upward, cold and indifferent. You felt a strange surge of energy, a hollow power that didn't feel like victory, but rather a heavy weight settling onto your shoulders.
Reader's Guide
In gameplay terms, EXP is awarded exclusively when a monster is defeated in combat. Each point gained contributes to the player's LV (Level of Violence). As LV increases, the protagonist gains more HP and their attacks deal significantly more damage to enemies. Lore-wise, EXP represents the absorption of a monster's soul or life force. It is explicitly stated that humans are the only beings capable of gaining EXP from killing monsters; monsters cannot gain it from each other in the same way. This mechanic drives the 'Genocide' route, where maximizing EXP is required to unlock the game's darkest secrets. Characters like Flowey and Sans understand the implications of EXP deeply. Sans often warns the player that their LV indicates how much they have hurt others, serving as a moral barometer. The system forces the player to constantly choose between becoming powerful through violence or remaining weak but kind.
Did You Know?
- The acronym 'EXP' is intentionally misleading; it does not stand for Experience Points in this universe, but rather Execution Points.
- Monsters can gain EXP from killing other monsters, as evidenced by the Royal Guard and other monsters having LV in the game's lore.
- Reaching LV 19 does not allow bypassing story events, and 'maximum destructive capability' is not a defined game mechanic tied to LV 19.
- The game's soundtrack does not change or distort based on a numerical EXP threshold; it changes based on player actions like killing specific characters or progressing through the Genocide Route.
