How do I show I have increased Resistance?

Hi.
Level 1 character.

If I am given a mutagen, like say Energy Mutagen (Lesser)
-Source The Fall of Plaguestone pg. 56
You gain resistance 5, add 1 point of damage on a hit with a melee weapon, and the duration is 1 minute.

How do I add/indicate this in HLO? I'd have to show the energy type too...??
I assume it's a temp adjustment of some type? (I've added an AC bonus for another buff I receive, so I'm familiar with that process). I don't see 'resistance" in the list-of-values?

Suggestions please?

You could use the Spell Adjustment for the Resist Energy spell as a workaround.

Find the Energy Mutagen item on the play tab, click the lightning bolt button, and check the "Drank" checkbox.

Hello.
So I first must 'add' the item to my gear.

Go to EQUIPMENT tab => Gear => Infused Alchemical Items => + for List of values => find/select/add for free, (they gave it to me, i carry it around until I use it)

This item now shows up in the PLAY tab, Gear.
select item, to get full description, there is a blank checkbox for "drank"
or
Just click the lightening bolt symbol of the item, which shortcuts to the blank checkbox for "drank".

The 'effect' now displays in the Play Tab/Combat section, with a heading 'energy resistances' = Resistance to {type} 5.

Thank you for the help.
