Diabolic Lure - Reaction

[aus] Reduce a bleed against you by 1.
[dai] Requires an infernal vampire. Only usable if this vampire blocks, before block resolution. Put 4 pact counters on the acting minion; if the number of pact counters equals or exceeds their capacity or cost, burn those counters to make them infernal.
[DAI] As [dai] above, and the acting minion's controller burns 1 pool.
