Danger Sense

"My danger sense be itchin." -Bug-Dude

You gain an uncanny ability to know when you're in any immediate danger. You feel an unmistakable itch in the back of your head under any of the following conditions:

• A ranged weapon, spell or projectile within 300 feet is aimed in your direction.
• Someone within 100 feet is intent on hurting you within the next minute.
• Someone within 30 feet draws a weapon.
• Something is going to explode in the next 12 seconds and you're in the blast radius.
• A large object is going to impact you in the next 6 seconds.
• Something is going to fall on you in the next 6 seconds.
• Anything the DM thinks would set off your danger sense.

When your danger sense goes off, you gain the following properties until the spell ends or the danger has passed, unless it lasts longer than 12 seconds, after which you lose the following properties:

• If the source of your danger sense forces you to make a Dexterity saving throw, as a reaction, you can give yourself advantage on that saving throw. After using your reaction, the spell ends.
• If the source of your danger sense makes an attack roll against you, as a reaction, you can force them to roll with disadvantage. After using your reaction, the spell ends
• As a bonus action, you can give yourself advantage on acrobatics checks for the next 12 seconds. After using your bonus action, the spell ends.
• A a bonus action, you can increase your speed by 15 feet for the next 12 seconds. After using your bonus action, the spell ends.
• As a bonus action, you can make a wisdom check to determine the general direction of whatever set off your danger sense. The DC is equal to your distance from the source of your danger sense in feet. If you succeed, you know if it is in front, behind, underneath, above, to the left, or to the right of you.

If you are concentrating on a spell, there is a 50% chance that your danger sense will not go off. If a possible trigger of your danger sense is undetectable by divination, it will not set off your danger sense. Once your danger sense has gone off 5 times, the spell ends.
