Lugh is quite likely the best hero in the game, getting him early is a massive advantage of its own
With the bless you are using I like to pair two Sidhe Lords in the same square, scripting one to
Bless->Mistform->Gift of Flight->Soothing Song->Holy Avenger->Attack Rear
And the other to
Protection->Mistform->Soothing->Soothing Song->Holy Avenger->Attack Rear
No gear, hasn't failed against any indie or PD I have seen yet.
