Notes
- "If foe initiates combat" means if a foe triggers combat during the enemy phase. The unit being initiated upon does not need to deal damage, nor be able to counterattack.
- However, if the effect is applied after combat, the unit being initiated upon must also survive it to fulfill this condition.
- The stat boost that can be applied during combat by Shield Session is considered a temporary buff.
