After asking the helpful alliance to wait on LAWs, (still seeking a second drop), an ally encountered a LAW, and when everyone waited, spent 31 BP to Ace, and deal 128 million, (not very impressive or efficient, ultimately, unless as an endurance test (of patience, and weariness at having been sent packing by Oracle so many times, often via rather impressive pyrotechnics .. One learns to fear the sound of spell-activation against LAWs, rather than welcome it .. The summary seems to be: not merely 'Get lost', but also 'And don't come back to Dodge any time soon!')).

And now back to hunting LAWs..
