Defend Kaer Morhen - Choice outcome?

In Kaer Morhen

at the meeting right before the fight against the Wild Hunt

I have to choose if I want potions or traps be made in the laboratory and if the wall or the forge should be repaired.

My questions here:

What will I get if take the potions?
What will I get if take the traps?
What will happen / will I get if I repair the wall?
What will happen / will I get if I repair the forge?

Update:

After I got the first answer I've to add that I need a more specific answer e.g. what sword/recipe would I get and do I have to place the traps by myself, are those usable items like bombs?

Best Answer

I went the traps and the wall. Both are automatic and reduce the numbers of battles needed. Used the YRDEN sign to close the portals (simpler than trying to toss bombs around). You get a sword and potion if you go the other options but unless you've got to the fight without exploring much of the rest of the game they're likely to be useless.
