Ahaha I have discovered the secret. If you have been searching for the secrets of victory, I have discovered it. Behold the revenant titan and all its D weapon glory!
In all seriousness this thing is beast and it will be a tough kill. Luckily its damn expensive. Watch this batrep from Frontline Escalation Batrep
Initial thoughts: Vendettas, vendettas will kill this fucker. So there is your answer. Or the baneblade with its own D weapon.
Fortifications can get void shields so this is a very tempting option (all in all I really like the fortification supplement)
But if you are only interested in competition and winning, well bring this, you prob have Taudar already so this will still fit in with it.
All hyperbole aside. This bastard is tough but not unbeatable. Get practice fighting it and you will be able to deal with it.
