The billowing flames of a dragon cover your feet, granting you explosive speed. For the duration:

• Movement Speed is increased by 20 feet.
• Movement does not provoke opportunity attacks.
• You can move through spaces occupied by others while under the affects of Flame Strider.
• Once per turn you can choose to leave behind a streak of flame up to 10 ft.  The space becomes lightly obscured until the start of your next turn granting half cover against ranged attacks that would occur across the wall.
• You leave a dim trail of light that lasts until the start of your next turn.  Allies moving along this trail gain +10 feet of movement during their turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher:

• You can leave behind a streak of flame up to +10 ft per spell level.
