Single-Minded Fury

You choose a single enemy as the target of your Single-Minded Fury. Your movement speed is doubled when moving towards your target plus you gain immunity to Slowed and difficult terrain. You also gain immunity to any mind-affecting effect that would prevent you from chasing or attacking your target. You gain a 1d4 bonus to accuracy rolls against that target, but suffer a 2d4 penalty to accuracy rolls against any other target. This effect lasts until the end of the encounter or until the target falls to 0 HP or lower.
