And the Summoned Hero will find that the meaningless parts of her task no longer stand within her way.
There is no more mandatory hammering of magic into an item, no long slow hard simple effort. There is still the effort, but a single great push will suffice, if she has the precision for it. Like a carpenter who now has the strength to hammer a nail into wood with a single mighty blow, instead of careful taps -- if only that blow be sufficiently exacting and precise.
Lesser crafters of Kekaro might find their work falling into the patterns and ruts of this world, easing their way. But as is often the case with Summoned Heroes, her Unique Skill will stand forever beyond that. In this aspect of Kekaro as she was in Golarion, she is without aid, without guide, without guardrails, without constraint.
Her mind, now, holds the patterns that she sets for it, in the crafting of arms and armor; she does not need to divert her attention to trying to refresh her memory. But that the pattern she envisions must be correct -- that remains her own task.
There is now nothing that stands between the Summoned Hero and perfection but herself; from this moment forward, any flaw in her work reflects nothing more or less than a flaw in her.
