League of Legends (LoL) Question: Thoughts on Abyssal Scepter for Taric?

I have been playing around with the idea of getting Abyssal Scepter on Taric recently. It does not provide any health or very good tank stats apart from the magic resist, but if both your team and the enemy's team are magic damage heavy, can it be a good pickup? Taric scales rather well with magic penetration himself too.
