Summoners, due to a technical issue, this week's series of Alliance Quests will be cancelled at 4pm PT. There will not be any Rewards for this series. The next series of Alliance Quests will start on April 18 at 12pm PT. We will be assessing the impact on Alliances and compensating accordingly, as well as returning Alliance Tickets.
6.1.2 Sentinel Mini Boss Counter
What are some of the best counters for this Sentinel before the Ultron? I know he has Bio Hazard which is going to be a pain. Only Ranked 5* Bleed Immunes I've got are Black Widow CW and IMIW at the moment, and I'm not sure if they're decent counters to this Sentinel. I can probably take my OR as well up, and will eventually for the Crossbones but I doubt if he'd be of any use against Sentinel. Any advise?
