The item War Ring has this rules text:
War Ring
Level 16 Uncommon
This steel band, emblazoned with a stylized sword, makes your attacks even more lethal.
Ring Slot 45,000 gp
Property: When you score a critical hit, deal 1 extra die of critical hit damage, based on the weapon or implement you wield. If your weapon or implement deals no extra damage when you score a critical hit, deal an extra 1d6 damage when you score a critical hit.
Power Daily (Free Action): Use this power when you score a critical hit with a weapon or implement. Add 2 extra dice of critical hit damage based on the weapon or implement. If your weapon or implement deals no extra damage when you score a critical hit, deal an extra 2d6 damage when you score a critical hit. If you've reached at least one milestone today, instead of rolling the extra dice of critical hit damage, deal extra damage equal to the maximum value of those dice.
If I have reached at least one milestone, does the daily power maximize only the 2 dice from the daily power, all 3 dice from the War Ring, or all critical damage extra dice, including those from the weapon itself?
