Chapter 326 - Sacrificial Edge

Broken was eager to fully explore the mechanics of the Gravestone Greatsword's first skill, Elemental Rune Cataclysm. Unlike the usual cast-and-forget abilities, this one had a more intricate system to master.

[Rune Charging: Runes are collected when the greatsword blocks attacks that exceed a certain damage threshold.]

To test the Rune Charging, Elincia launched a magic skill, and Broken braced himself to block the attack. She started with a single magic missile, which didn't pose much of a threat. It was fast, but Broken, now fully accustomed to the greatsword's weight, easily blocked it. 

The impact was negligible, and he took no damage. However, no rune appeared from blocking the missile. 

They guessed the damage might have been too low to trigger it. So, Elincia fired off multiple magic missiles at once. After blocking them all in rapid succession, a single rune finally began to charge.
