I've played numerous matches were a warlock cast novabomb down a long corridor without aiming at anyone or anyone even being there just for the novabomb to auto target and track a random player who happens to walk into that corridor or spawn at the end of the corridor. So ya it's got infinite range and similar to jotun, it has auto targeting and tracking, while BB requires your target be within 30 meters to track and doesn't have auto targeting. Additionally BB can be dodged if your target is fast moving, literally every blade will miss. The tracking is also dumb and will track targets behind cover resulting in situations were you try to kill them with the AOE by throwing blades around the cover, but instead the blade all hit dead center of the cover and deal zero damage to the enemy. BB is also very buggy and you typically need 3 blades to land to get the kill, especially if they have and overshield or 10 resilience.

No, you need one blade to hit to get the kill.

I've had it happen numerous times where I've landed 1 or 2 blades and the players survived. As I recall from bungies last twab which discussed BB damage, it deals 40 impact and 60 explosion for a total of 100 damage per blade, meaning you need 2-3 hits for a kill.

Why is it that I am one tapped by the blast damage from blade barrage at 100 resil then? I don’t even have to get hit by the actual blades
