Shadow Veil is a spell within the Arceuus spellbook that requires 47 Magic and completion of A Kingdom Divided quest to be cast.
While under the effects of Shadow Veil, players have a 15% chance to avoid being stunned and damaged while pickpocketing NPCs. This stacks multiplicatively with the dodgy necklace, where Shadow Veil will attempt to avoid the stun first for a total of 36.25% chance to not take damage from a failed pickpocket. The effects of the spell remain active for a duration ( seconds), where is the player's Magic level at the time of casting. Players can only cast Shadow Veil once every 30 seconds. (Resulting in level 50 Magic providing 100% uptime via lasting the full 30 seconds to cast again. Higher Magic levels will reduce the need to cast as often.)

If that fails, the NPC shouts, and then the necklace does its 25% roll.
So your chance of dodging the penalty is indeed the 36.25% you calculated, and you can see which one happened to you."
