So, you need to maintain "spells = effects" to make the argument conclusive. But:
"ArM5 p.98 [i:
Instilling Effects[/i]"]The effects instilled in enchanted items are designed like spells, but they are not spells.
This holds especially for ArM5 p.99 Linked Trigger effects, which can't be just replaced by spells.
If you wish to rule around this, best discuss this with your troupe.
