I can elaborate a bit on the Justicar Bubble, because it doesn't follow the normal rules for primes and detonations, at least not entirely.
The Bubble will prime and detonate, but it's important to understand the nature of both is altered slightly because of the bubble's unusual properties.
Casting a Bubble will:
- Stagger up to 4 enemies within the AoE upon deployment
- The Bubble will apply Warp to up to three targets. If one (or more) of those targets is primed, the Warp effect will detonate an explosion depending on the nature of the prime, however this effect is only ever applied at the moment of deployment. The Justicar Bubble, once deployed, can no longer detonate unless it is redeployed (it is a one-time effect per casting.) It will also apply all of Warp's basic, normal effects to those targets, such as DoT (ie it has the effects of a level 1 Warp, although it is considered to be at the Bubble's Rank for BEs.)
- The Warp effect will "prime" any remaining targets that were not already primed (in other words, you can detonate one target while priming two others. With the radius evolution and a very small BE radius, it might be possible to detonate 2 targets if they were diametrically across from each other, but I don't know for sure.)
- The Warp effect only applies while the targets are in the bubble. As soon as they move outside the bubble (or it is re-deployed) they are no longer primed. Warp's normal duration does not apply, only the bubble's duration.
- Enemies are primed as soon as they enter the bubble, but only if there are not currently 3 targets under the bubble's effects.
I assume that the Warp effect's priority as a primer functions the same as for the power Warp, which means that subsequently-applied primes will be detonated first, after which (assuming the target doesn't leave the bubble) the Warp can still be detonated.
