Since January, there were plenty of additions to the legion. Today there is a special piece – the Aeonic Orb. Somewhat more graceful than the Abattoir, I find this the actual supreme piece of the army. Having only one weapon, it’s flexibility is still great. You may choose between a massive barrage weapon, no foe wants to get exposed to, or a strong TK shot, to take out titans. Being skimmer helps, as this means popping up to take shots is possible in cheeky Eldar manner. Other than that, the Aeonic Orb makes a brilliant blitzguard and BTS. It’s portal also means, a safe heaven for damaged infantry that has to retreat to marshal. Also quick support against fast enemy formations is granted and makes it even more flexible. I would not necessarily put it in every list, though it’s always worth considering – even if it’s just for the sake of seeing the fear in your opponents eyes, while trying to avoid this war engine at any cost.
