Stats

Stats are values that affect encounters. They are usually increased with LV or equipment, but some can be altered by other methods.

HP

HP (Hit Points) function similarly to Undertale. Clover starts with a maximum of 20 HP and can only increase this through increasing their LV. HP can be restored at SAVE points, through consumables, or by touching green attacks. They can also be restored by a successful shot with the Glass Ammo equipped or when using certain acts during the final boss fight of each route. Clover loses HP when damaged in a fight. They also are knocked down to 1 HP after crashing off of UG Aviator, Martlet's raft. Hitting 0 HP causes a game over and makes Clover reload from their last SAVE.

In the Wild East Clinic, Clover can supercharge their HP by paying 30G. This puts them 15 over the maximum. They can only repeat this process after their HP has dropped to their normal maximum or below.

AT

AT (Attack) is the damage Clover deals in battle. It has two components, primary and secondary. Primary AT starts at 10 and can only be increased by increasing Clover's LV. Secondary AT starts at 0 and is the amount of damage specific ammo does.

More damage is dealt the closer to the center Clover hits in the FIGHT interface and the more of the rings they successfully hit with certain ammo or the Wild Revolver. A perfect hit with the Wild Revolver also does more damage than a perfect hit with the Toy Gun. Once a monster can be killed in the next turn with a maximum damage attack given Clover's and the monster's stats, they will always be killed if Clover successfully shoots them again no matter how little damage Clover deals. If the monster has been damaged in battle before they reach this point, they become spareable.

DF

DF (Defense) is the damage Clover resists during battle. Similarly to AT, primary DF starts at 10 and is increased with LV while secondary DF starts at 0 and is increased with accessories.

Unlike Undertale, which takes 1/5 of Frisk's defense into consideration when calculating resistance, Undertale Yellow calculates more directly. Every 1 DF is equal to 1 HP protected against when Clover takes a hit. This makes DF much more useful in Undertale Yellow.

On Easy Mode, the Worn Hat and Nice Hat increase defense by 3.

EXP / LOVE

EXP stands for Execution Points, though this is not explained in Undertale Yellow. It is increased by killing monsters. Killing robots, with the exception of Axis, does not grant EXP, and neither does killing Ceroba Ketsukane in the Flawed Pacifist Ending. Like in Undertale, when killing Flowey at the end of the Genocide Route does not grant EXP.

LV, also known as LOVE, stands for Level of Violence, which is not explained in Undertale Yellow either. It is analogous to the levelling system in many RPGs and controls maximum HP, primary AT, and primary DF. It is increased by reaching certain EXP thresholds. On the Genocide Route, the Axis battle automatically levels Clover up from their current LV (either 12 or 13, depending on monsters killed beforehand) to LV 19.

PP

PP (Protection Points) are the amount of hits that Clover is immune to. They are increased in one of three ways. The first is by eating the Golden Pear, which increases PP by 2. The second is, if Clover's PP is 0 and they start a battle in the Steamworks when Ceroba Ketsukane is accompanying, Ceroba increases Clover's PP by 1. The three exceptions to this are the Macro Froggit battle, where she is never present, and the Guardener and Axis fights, where she shields them partway through as soon as she becomes able. The third is using the Hope act during the Ceroba Pacifist boss battle, which increases PP by 1.

SP

SP (Speed Points) are the amount of turns that Clover's SOUL will move faster in battle. Drinking the Sea Tea, making a successful shot with the Coffee Bean Ammo, or using the Remember act during the Ceroba Pacifist boss battle increases this by 1. Drinking the Golden Coffee increases this by 3.

RP

RP (Restoration Points) are the amount of turns that Clover will recover HP for. They can only be increased by using the Golden Cactus, which increases RP by 3.

Stat Chart

Until LV 20, HP is calculated as 16 + (4 × LV), AT is calculated as (2 × LV) + 8, and DF is calculated as (LV - 1) ÷ 4 + 10, rounded down. Unlike Undertale, the AT and DF shown in the Stats menu match their internal value.

Trivia

• Levels 14 through 18 are only able to be seen when rapidly leveling up at the end of the Axis battle on a Genocide Route. The stats of these levels, excluding HP, are not visible in normal gameplay but are still set internally.
• There are maximum values in place for SP, RP, and PP, preventing these values from exceeding 99. Despite being impossible to change ingame, these values are saved to the save file as stats, similar to max HP, allowing modification of these limits.
  • PP and SP cannot reach these values during normal gameplay, as there are no ways to renewably and indefinitely increase them. However, due to a glitch, RP is never properly saved at any point, and only reset following an overworld load, allowing it to be indefinitely accumulated until its maximum by dying, then using the retry feature before the effect wears off.
