When two separate hits deal damage while you are concentrating, resolve each damage event and check in order. Do not pool the turn’s damage into one difficulty. In this example, a hit for 6 requires DC 10; a later hit for 22 requires DC 11 if concentration remains active.
Order determines whether the effect still exists
Fictional D&D 2024 case: your character is concentrating on a spell and takes a first hit dealing 6 damage after damage resolution, without reaching zero HP. No special feature or effect changes these checks. Half of 6 is 3, so the Constitution saving throw’s DC is 10.
If the save succeeds, the effect continues. A second, separate hit then deals 22 damage after resolution, again without reaching zero HP. Half is 11, making this second save’s DC 11.
If the first save fails, concentration ends then. Do not make a second save to maintain an effect that has already ended, or treat the later result as restoring it. Update hit points for both damage events even if concentration ended earlier.
Twenty-eight answers a different question
The example’s damage totals 6 + 22 = 28. That helps check the total HP loss from those two hits under the stated conditions. It does not combine two separate impacts into one 28-damage hit or produce a single DC 14 check.
The official 2024 glossary requires a save when taking damage to maintain Concentration: DC 10 or half the damage rounded down, whichever is higher, up to DC 30. Each hit here happens and resolves separately. This example does not define how to split damage types within a single impact.
Keep one note row per hit
DnD Dynamic Sheet documents hit points, notes, spells and custom counters. You can retain a manual note such as:
| Example event | Damage | DC | Pending resolution |
|---|---|---|---|
| First hit | 6 | 10 | Save; confirm whether the effect continues |
| Second hit | 22 | 11 if still active | Resolve only while concentration remains |
The table contains no actual rolls. Add each real save total and whether the effect continues or ends. Do not reuse the first result as if it covered the whole turn.
What the sheet alone does not establish
Writing “concentration” in a note does not make the save. This guide does not claim the app detects hits, counts sources, calculates the DC automatically or ends spells without your involvement. Confirm the result with your table and update your character’s record.
For calculating a single damage event, see the concentration DC guide. DnD Dynamic Sheet is a paid Windows beta; consult capabilities and activation and the product recordings before choosing it. This article explains a rules-and-recording decision, not an interactive app test.
