Shadow Weave Magic

You have learned how to cast spells using Shar's Shadow Weave, sacrificing your connection Mystra's Weave:

• Insidious Magic. Divination spells cast against you and your spells must pass a Spellcasting ability check (DC equal to your spell save DC) to detect you, failure reads you and your spells as non-magical. (ex: an illusion of a rock wall would appear to be a real rock wall until interacted with.)
• Pernicious Magic. Your dispel magic and counterspell are treated as one level higher than the spell slot used (ex: 4th level counterspell acts like a 5th level counterspell)
• Tenacious Magic. dispel magic and counterspell are treated as one level lower than the spell slot used against your Enchantment, Illusion, and Necromancy spells.

Your Enchantment, Illusion, and Necromancy spells increases their DC's by +1 and their attack rolls by +2, however your Evocation and Transmutation spell decrease their DC's by -1 and their attack rolls by -2. In addition, any spell effect that creates light instead creates darkness. Your DM may decide this effect can change the spells outcome. (including causing the spell to fail, ex: your DM may rule Dawn deals no damage or deals necrotic damage now.)
