I tested her Consecrate ability on Steam.
I built one Crossbow Fort and upgraded it with tier 3 Barrage.
To an unarmored Gorillon, it dealt 31-40 (avg. 35) damage per bolt without Consecrate, and 39-50 (avg. 45) damage per bolt with tier 3 Consecrate.
To a medium-armored Saurian Myrmidon, it dealt 12-16 (avg. 13.5) damage per bolt without Consecrate, and 15-20 (avg. 17) damage per bolt With tier 3 Consecrate.
At least on my tests, the other towers' abilities remained unchanged regardless of Consecrate. Namely, Wasp Missiles, Totem of Weakness, Critical Mass, and Furnace Blast.
