Magical Defense:
* Counter-spells: Directly opposing the dark spell with an appropriate spell of light or protective magic.
* Shields: Creating a magical barrier that deflects or absorbs the incoming spell. This could be a simple energy shield or a more elaborate construct like a wall of force.
* Enchantments: Items like amulets, rings, or weapons imbued with protective magic that can automatically resist or deflect dark spells.
* Wardings: Placing magical seals or runes in a location to prevent dark magic from entering or affecting the area.
Non-Magical Defense:
* Physical Barriers: Using strong materials like stone, metal, or even reinforced concrete to create a physical barrier against the spells.
* Isolation: Preventing the caster from reaching the target, either through distance or by separating the target from the environment (like trapping them in a magically sealed room).
* Disruption: Using physical means to interrupt the casting of the spell, like a sudden loud noise, blinding light, or even a physical attack on the caster.
Mental Defense:
* Willpower: Resisting the spell's effects through sheer mental fortitude.
* Protective Rituals: Using meditation, prayers, or other practices to strengthen the mind and resist the influence of dark magic.
Other Factors:
* The Caster's Power: The strength of the dark spell is directly related to the power of the caster. A weak caster will have a weak spell, making defense easier.
* The Target's Vulnerability: Some individuals might be more susceptible to dark magic due to their own weakness, fear, or lack of mental fortitude.
