Techno-Smithy question

[5IronBadger]

Hi all,

I could not find an answer to this in all my searching so I was hoping for some feedback.

What is the PPE cost for the Techno-Smithy when using Talisman Creation or Forge Magic Weapons and Armor?
Is it just the cost of the spells they are enchanting the items with? I am assuming they need to spend PPE for those spells (it wasn't specified).

These are two abilities that rely on percentile roll for success. Based on what I am reading it does seem the Techno-Smithy would have to cast Enchant Weapon (minor) when using Forge Magic Weapons and Armor. But then what are "spell like abilities" are those spells? What do they cost PPE wise?
With the Talisman creation; do they have to cast the Talisman spell?

I appreciate any clarity that any of you can offer.
I realize that as the GM I can do whatever I want, but I wanted to understand the authors original intention. Which I don't.
