Benefit: When you use your speed of thought, you can enter an enemy's space. Doing so ends the movement. You must then slide the enemy 1 square.
Unless a Battlemind takes the Zephyr Blade paragon path, which allows speed of thought to avoid provoking opportunity attacks, then moving from a square adjacent to an enemy into an enemy's space should provoke an opportunity attack.
Does using Linebreaker cause an unmodified speed of thought move to provoke an opportunity attack?
