Unable to Replace Warlock Spell

[Purest Warrior]

Leveling up from level 2 to 3, I am able to replace a known spell with a new one, but I can only choose from three of the four spells that I know. What am I missing here?

Edit: It's "Invocation: Armour of Shadows", which apparently doesn't take up a warlock spell slot.

Armour of Shadows is not a spell you unlocked through the normal spell route, but unlocked through a level up selection (which is bound to an ability at level 2).
Therefore, you cannot replace it.

Thanks. So I screwed up by picking that at levelling up to 2? It seems fairly useless, seeing as I can't use it while wearing armour.

To change the Endritch invocations you need to "reset class" with Withers, and simply choose warlock again, so you can choose your invocations all over and unmake "mistakes".

I personally always start with the two blast ones because they are the ones to be most useful at the start of the game. Unless you are making a pure chat character, which then you use those related ones and get a character who is not already proficient in persuasion/deception/etc.

But in any case, you need withers and the whole "change but not change your class".

Alright. Thank you for your help.

Just to be clear, Eldritch Invocations are not spells, though it is possible you can be given 'special' (non slot consuming) spells by choosing invocations. So when you get to replace spells ... this doesn't mean you can replace invocations. BTW, you CAN redo your choices with respec as others have said above, but it's tedious esp. at higher levels. Basically, when it comes to invocations, "choose wisely".

Yes, it's not entirely clear where a given ability actually comes from (even though I picked it myself). They can come from a variety of different sources, it seems. A GREAT variety of different sources.

When I last played D&D (or AD&D, as it was), all spells were replenished at resting and there were no "half-rests", eldritch invocations, sub-classes with innate abilities, etc., so I am still trying to get my bearings here.

Thank you for your help and advice.

...hrm, that's an interesting deviation from tabletop.

Additionally, when you gain a level in this class, you can choose one of the invocations you know and replace it with another invocation that you could learn at that level.

That's a default rule ( https://www.dndbeyond.com/classes/7-warlock ).

Wonder why Larian chose not to implement that, even though they allow a full respec (well, almost everything; ability scores, classes and everything derived from classes. But not, say, respec'ing ancestry.)

FWIW, when you've got access to Withers, the respec nominally costs money but is effectively free because he doesn't mind at all if you pickpocket the gold right back.
