Counter-Productive

A) I'm wondering if a dagger + Reverse Rune would make a property of being able to resist damage, then fusing that with the armor. Don't want to screw it up and make the armor stab the wearer

B) Using an accelerate rune would probably make the armor just good right out - but we'll run out of Accelerate runes if we just use them for everything.

C) Could we just shrink rune some metal (to make it lightweight) and fuse it or craft it into the armor?

Dagger + Reverse Rune + Costume = Armor?



Good puzzle logic, but you're worried that a Reverse rune might just make the dagger rusty and blunt. You wouldn't want to combine that with anything wearable.



Using an accelerate rune would probably make the armor just good right out - but we'll run out of Accelerate runes if we just use them for everything.



That might work, but you're already out of Accelerate runes, remember?



Could we just shrink rune some metal (to make it lightweight) and fuse it or craft it into the armor?



Now you're on the right track!

Although shrinking the components doesn't affect the weight of the final product, and there's also the bigger size difference = more MP cost to consider, you could probably combine any article of clothing with a ring or some other smooth metal to craft makeshift armor.

You're going to need a Grow rune for this.



->



You combine the Grow rune with one of the rings. This should reduce the MP cost significantly, although it will still probably take all your MP to combine with the robe.

You wait for your MP to regenerate to full.



->



It took your entire MP bar, but you managed to craft the CULTIST BATTLEMAGE COSTUME. This should provide more defense than a flimsy robe, in addition to looking just a bit cooler. You hope your customer likes it!
