[ED3] Spell Design Knack

[Flash]

My Nethermancer in our online ED3 Heroes Unchained (link below in signature if you wish to enjoy some Earthdawn reading) game is about to hit 5th Circle. In preparing for that I attempted to convert the EDC Spell Design Knack to ED3. Wasn't much to change but I thought I'd run it by everyone here as well. Please let me know if you see anything glaringly wrong. Thanks.

Spell Design Knack
Talent: Spellcasting
Rank: 7
Strain: 0

The Spell Design talent knack allows magicians to design new spells for their Discipline. Unlike most other talent knacks, Spell Design does not cause Strain or require a specific result level on the adept’s Spellcasting Test. The Spell Design knack simply allows magicians to use their Spellcasting talent to design spell patterns as described in the Spell Design rules. This talent knack is learned separately for each spellcasting Discipline.

I would think this is something they could do without a Talent Knack. That being said, I think the Knack is fine as written.
