Eidetic Recollection Investigator Talent and Inspiration use.

[Nadlor]

Investigators can expend one use of inspiration from their pool to add 1d6 to the result of a skill check, including any on which they take 10 or 20. If the skill is a trained knowledge skill, adding the 1d6 doesn't expend a use of inspiration.

According to the Eidetic Recollection Investigator Talent, an investigator may expend one use of inspiration to take 20 on a Knowledge skill check. When this happens, is the additional 1d6 also applied, or is it substituted by the automatic 20 and therefore no inspiration dice is added to the check result? If this is the case, spending the use of inspiration could entail a lower check result, especially when things like amazing/tenacious inspiration are added to the mix.

Thanks in advace for your input!

The way I would rules this case, is that they are separate ability uses.

A) You can spend 1 use to add 1D6
B) You can spend 1 use to take 20 on a Knowledge skill check.

So in the case of your specific question, if you use Eidetic Recollection, you would be able to take 20 on a knowledge skill check. (trained or otherwise). I would argue that you could then spend a second use, to add 1D6 if you wished... but again, they are different abilities that each expend a use from the pool.

you could do both if you wanted

Ok. The thing is that adding the 1d6 is free for trained knowledge checks (using inspiration this way doesn't expend any uses of the inspiration pool), so for trained knowledge checks the 1d6 is always added. With Eidetic Recollection, I assume that if I decided to spend the use of Inspiration I would end up wicth a check of 20 (automatic 20 because I spent one use of inspiration) + 1d6 (another use of inspiration, which is free and doesn't expend the pool) + skill modifier, correct?

Thank you for your input!

yup

I dont remember if it lets you "take 20" on untrained knowledge checks or not... but basically, yes, you are correct.

If its untrained 20 + skill mods.
If its trained 20 + skill mods + 1D6 (provided you have a use left).

At least this is how I would use it. The 1D6 functions much like the monk abilities that function so long as you have points in your ki field.
