I have a 5 4 1 widow and she has been a real help for Ultron. the ability to selectively destroy those bomb tiles is very nice. With a 2 or 3* thor at 5 yellow makes that green easier to pop off.
i really just started playing her this event as i got the 5th green as a daily reward recently.
i was wondering if a 544 build would be good for her since that allows 3 shots on red and a guaranteed match 5 on purple.....or is that just crazy talk?
At 5 covers, Pistol clears three 3x3 blocks of tiles. It deals 869 base damage plus whatever damage Widow would do with the cleared tiles. It's really just for clearing troublesome tiles and generating cascades. It functions just as well at 3 covers, and her other abilities are much better at 5 covers.
