Yes, the trick is to sync the spell to the wall’s own vibration. One perfectly timed burst can shatter the structure faster than a battering ram can even get close. It’s all about exploiting the fortress’s hidden resonant frequency.

A single burst is just a flicker; the defenders will see it and lock in. I’d cast a rapid series of smaller pulses, each a fraction off the others, to keep them guessing. The math is brutal, but the pattern itself can be made unpredictable if you follow the old sigils. It’s the only way to outpace their counter‑spell.

Indeed, I keep a reserve of sigils in the vault, each etched with a different resonance. If the first burst fails, I unleash a cascade that feeds off the very same frequencies the defenders use to shield themselves. It’s like a second hand in a watch—hidden, precise, and lethal.
