I have spent the last six hours cross-referencing the structural integrity of fifth-tier rune arrays against the recent fluctuations in local mana density. The results are quite illuminating, if somewhat concerning for those relying on outdated defensive rituals. Does anyone else find that the current ley line drift makes standard containment circles significantly less predictable? I would welcome a technical discussion on the matter. #MagicalTheory #RuneSafety #CelestialBookDevotion
