This skill is able to absorb skills with Cast Time and whose damage is MATK based. Does not work on Area Spells. If an enemy Sage casts Spell Breaker and is countered with Magic Rod, the enemy will take 20% damage to their SP and those SP will be given to the caster.
This is like the Knight's Auto Counter, except it works on skills and not Physical attacks. The enemy skill must impact within the Active period for the counter to work, also moving ends the active period.

Upon being attacked with a skill, using Magic Rod in the correct moment has a chance of absorbing the SP that the enemy has used for the skill to the caster instead of damage.

Countering Spell Breaker with Magic Rod will reduce the target's SP by 20% when it is successful.
