artificer spell slots - DnD 5e Artificer Subclass Breakdown slot jago 888

Now notice it doesn't say an ARTIFICER spell slot, but just "Spell slot". Couldn't you expend a Warlock spell slot, if you had them, instead?

The Artificer's spell list takes a lot from the Wizard's spell list, but also includes several excellent options from the Cleric spell list. Similar in many ways to the Bard, but artificer spells include more of the non-hp healing options than the Bard does.

If we're talking about 1st level the Artificer has the same two spell slots as the Cleric, Druid, Bard, Ranger, or Paladin. Those same 2 slots use Cure Wounds for the same healing.
