+* `reducedhp` is also reset when a `deadFunction` (<img src="https://static.atlasacademy.io/NA/BuffIcons/bufficon_350.png" alt="Trigger skill on Death" title="Trigger skill on Death" height="20" width="20"> [Trigger skill on Death](https://apps.atlasacademy.io/db/NA/buffs?type=deadFunction)) or a `gutsFunction` (<img src="https://static.atlasacademy.io/NA/BuffIcons/bufficon_365.png" alt="Trigger skill on Guts" title="Trigger skill on Guts" height="20" width="20"> [Trigger skill on Guts](https://apps.atlasacademy.io/db/NA/buffs?type=gutsFunction)) activates. For example, as seen in [this video of the behaviour in Valentine's 2023 (NA) CQ](https://www.youtube.com/watch?v=CGVNWn8ZBRc), the observed charge gain on Romulus-Quirinus's Arts card is **54.15%** with the card dealing **0** overkill hits on Artemis; however the expected charge gain should be **72.19%** with the card dealing **2** overkill hits on Artemis:
+
+    | &nbsp; | Enemy HP | `reducedhp` before arts card | Damage dealt | `reducedhp` after arts card | Overkill (`reducedhp` > enemy HP)
+    | - | - | - | - | - | -
+    | Expected | `84543` | `68435` | `67922` | `136357` | true
+    | Observed | `84543` | `0` (reset) | `67922` | `67922` | false
+
+    i.e. The `reducedhp` *should have been* `68435` *before* the first hit of the arts card; this would have made the `reducedhp` *after* the arts card (`136357`) greater than the enemy HP (`84543`). This is what the first row in the above table shows. However, as we see in the second row, the `reducedhp` was reset by the time the arts card hit; meaning that the *actual* `reducedhp` *after* the arts card was merely `67922` (which is not greater than the enemy HP). Thus, no OK hits are observed on this card.
+
+    > **Note**
+    > It is likely that there are functions apart from `deadFunction` and `gutsFunction` which can reset the `reducedHp`

 ### Enemy behavior after killing taunt servant
 
 With the 2.0 update*, DW fixed this enemy behavior to be mostly consistent. Enemy will stop attacking after killing the taunt servant except for the following case:
