Notes[ | ]
- Has the same effect as
Death Blow 2. - "If unit initiates combat" means if the user starts combat during the player phase. The unit does not need to deal damage, nor be the first to attack.
- However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
- The stat increase that can be applied by Death Blow Echo is considered a temporary buff.
