Using PC stats in a macro for an NPC stat block

I've just finished rolling up a 5e level 4 Battle Smith Artificer and have been creating the stat sheet for the Steel Defender. For sections such as the the Hit Points and Actions I have no problem using @{Charactername|pb} to use my character's proficiency bonus in the stat. However for the Saving Throws, Skills, and Passive Perception I can't get it to do the same. Any advice on how to accomplish this would be appreciated.

1. Which character sheet are you using?

2. What macro are you using? It's helpful if you post it in its entirety, not a screenshot/picture. The best way is to post it using the 'code' styleblock.

I think they are talking about how to adjust the NPC sheet to use those values, so as the character levels up, the companion's abilities reflect that. I think a lot of it will need to be done manually. Most of the NPC values are manually input since they don't always follow the same build rules as PCs. Fortunately, your PB will only likely change a few times during the course of a campaign, so it's probably not too much of a hassle.

You could set the Steel Defender to a PC sheet instead of NPC, and add your character's @{pb} as a global saving mod/damage mod/whichever things it increases. You'd need to either use macros to access the NPC actions for the attacks, or re-enter them into the Attacks & Spellcasting section, though.
