6 rulings from Wizards of the Coast
- 24 November 2014Prowess goes on the stack on top of the spell that caused it to trigger. It will resolve before that spell.
- 24 November 2014Prowess triggers only once for any spell, even if that spell has multiple types.
- 24 November 2014Casting a noncreature spell will cause both prowess and Monastery Mentor's other ability to trigger. You can put these abilities on the stack in either order. Whichever ability is put on the stack last will resolve first.
- 24 November 2014Any spell you cast that doesn't have the type creature will cause prowess to trigger. If a spell has multiple types, and one of those types is creature (such as an artifact creature), casting it won't cause prowess to trigger. Playing a land also won't cause prowess to trigger.
- 24 November 2014Once it triggers, prowess isn't connected to the spell that caused it to trigger. If that spell is countered, prowess will still resolve.
- 24 November 2014The spell that causes Monastery Mentor's second ability to trigger will not cause the prowess ability of the Monk token that's created to trigger.
