Warlock and spell slots RAW

[Gabriel Pendragon]

"all of your spell slols are the same level."

This is right out of the warlock block for their spells. Does this make all spells warlocks get from any source the level set in the warlock block? The wording does not specify warlock spells.

Obviously this is not intended, or it would be ridiculous. But this is what is written.

From the multiclassing section in the PHB:

Pact Magic. If you have both the Spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the Spellcasting class feature, and you can use the spell slots you gain from the Spellcasting class feature to cast warlock spells you know.

So yes, when you cast a spell you have access to from another class (gained from the spellcasting feature, at least), it would be cast at the Warlock's Pact Magic slot level, as intended.
