Can you activate reactions during your own Awaken/Beginning phase without triggers, and does a temporary dying trigger a chain where you can activate reactions?

Ruling: You cannot activate reactions during Awaken/Beginning phase without a trigger creating a chain. A temporary dying is specifically a trigger in the beginning phase, so you can react to it.

Sequence:

• Temporary triggers to die at beginning phase
• This creates a chain
• You can activate reactions (like hidden) in response to this trigger

Nuances:

• Reactions require a trigger to open a chain; they cannot be activated freely during Awaken/Beginning phase
