The fight mainly depends on your skill, but the RNG can really screw you over.
- I’m not sure under what circumstances the cocoon has a pretty low chance of becoming immune; when it reaches zero, it won’t die and will normally hatch.
- The frontal attacks aren’t always static. If the boss targets Brann at a moment when he’s jumping, the frontal will follow him until it finishes, probably killing you in the process.
- When Brann has the aggro and for some reason decides to go to the entrance, which is relatively common, he might jump and exit the room, resetting the boss. (EDIT: It also happens because Brann suddenly decides to go to the stone and start his “Waiting” channel, epicly going through the wall and resetting the encounter.)
Zekvir is not the true seasonal enemy; it’s Brann.
