Does a concentrating caster hit by Ice Knife require 2 concentration checks?



As the ice knife can to damage in two separate ways, with one defined to happen after the other, would a caster damaged by both need to make multiple concentrations checks?

The caster would need to make up to two saves.



The SRD says this about Concentration (emphasis mine):




Whenever you take damage while you are concentrating on a spell, you must make a Constitution saving throw to maintain your Concentration. The DC equals 10 or half the damage you take, whichever number is higher. If you take damage from multiple sources, such as an arrow and a dragon’s breath, you make a separate saving throw for each source of damage.




Further, Jeremy Crawford has ruled that the Magic Missile spell provokes separate saves for each missile.




Concentration: "You make a separate saving throw for each source of damage" (PH, 203). Roll for each missile.




Since Ice Knife deals damage twice, you would indeed make two saves, but only if they fail the DEX save for the secondary damage.



This is supported by how and when we roll for damage. We roll damage as soon as we hit with an attack:




  1. Resolve the attack. You make the attack roll. On a hit, you roll damage...



So, we have the initial attack roll, for which we roll damage on a hit. THEN, we have an independent DEX save, which is a separate damaging event. We've already attempted to deal damage once, and now we attempt to do so a second time.

    How are two damage instances from a single spell not "from a single source"?

    The two damage events are discreet because one is checked on the attack roll and the other requires a separate saving throw, which happens independent of the attack roll. Jeremy Crawford mentions in his ruling for Magic Missile that each missile of that spell provokes separate rolls, and I would consider that spell significantly more ambiguous than Ice Knife

    @CaptainMan that would be one thing (the sword) dealing damage, you just roll extra dice for the attack, and that much damage is of a different type than the rest. Spells like Flame Strike are also examples of this, where each successful hit results in Fire + Radiant damage from the same hit. What makes Ice Knife unique is there are two independent attempts to cause damage: 1) the attack roll, which may or may not hit and deal damage, and 2) the explosion and DEX save, which also may or may not deal damage. Both are distinct, hence two saves.

$begingroup$

Yes. Two saves may be required.



Two concentration saving throws are required as there are two discrete damage instances. In addition to being explicitly stated as separate and ordered damage in the ice knife description, "Hit or miss, the shard then explodes", they're also completely different mechanics.

    The Ice Knife deals two types of damage, but is a single source of damage.



    The PHB p203 states:




    If you take damage from multiple sources, such as an arrow and a dragon's breath, you make a separate saving throw for each source of damage.

      Concentration also says "Whenever you take damage," and since these are two discreet damage events, you would still need (up to) two saves.

      $begingroup$
      Flame Strike is an example of a spell that deals two different damage types and IS only one source of damage, but a spell like Eldritch Blast is also technically "one source," and deals one type of damage, but can have multiple attack rolls, and thus multiple damaging events, like Ice Knife. The types of damage are irrelevant, it's how the damage is dealt that matters.

    $begingroup$

    I would argue 2 concentration checks are needed, since if one passes the dex saving throw they don't take the cold damage whatsoever. That being said, for this to happen the caster must hit the target, and the target must fail the dex save for 2 concentration checks to be required. The DC for each is relative to half the damage taken (for scaling purposes as the lvl increases), or DC 10, whichever is higher.

    @CaptainMan that would be one thing (the sword) dealing damage, you just roll extra dice for the attack, and that much damage is of a different type than the rest. Spells like Flame Strike are also examples of this, where each successful hit results in Fire + Radiant damage from the same hit. What makes Ice Knife unique is there are two independent attempts to cause damage: 1) the attack roll, which may or may not hit and deal damage, and 2) the explosion and DEX save, which also may or may not deal damage. Both are distinct, hence two saves.

    Yes. Two saves may be required.



    Two concentration saving throws are required as there are two discrete damage instances. In addition to being explicitly stated as separate and ordered damage in the ice knife description, "Hit or miss, the shard then explodes", they're also completely different mechanics.

            The Ice Knife deals two types of damage, but is a single source of damage.



            The PHB p203 states:




            If you take damage from multiple sources, such as an arrow and a dragon's breath, you make a separate saving throw for each source of damage.

              Concentration also says "Whenever you take damage," and since these are two discreet damage events, you would still need (up to) two saves.

              Flame Strike is an example of a spell that deals two different damage types and IS only one source of damage, but a spell like Eldritch Blast is also technically "one source," and deals one type of damage, but can have multiple attack rolls, and thus multiple damaging events, like Ice Knife. The types of damage are irrelevant, it's how the damage is dealt that matters.

            I would argue 2 concentration checks are needed, since if one passes the dex saving throw they don't take the cold damage whatsoever. That being said, for this to happen the caster must hit the target, and the target must fail the dex save for 2 concentration checks to be required. The DC for each is relative to half the damage taken (for scaling purposes as the lvl increases), or DC 10, whichever is higher.
