Id say stacking a few Dorans rings is a much better investment than Abyssal.
If you seriously want MR, grab one Negatron cloak, other than that everything is in how you play. If you dont want to lose to LB and Akali mid, gank them, especially as Xerath you can provide a stun and a lot of burst damage, he is a good lane to gank for.
