The concept isn’t that bad because throughout the pathway, there are few nexus portals along the path to boss so that if whatever in front becomes difficult, they can retreat to nexus through the portal. It makes the gameplay challenging and possibility of easier to die more fun to play. Another idea is bosses with few randomised behaviour that can mix and match and can create a very deadly combination.
The boss will choose one of each behaviour randomly.
Debuff (Movement): Paralyse, Confuse, Petrify, Slow
Secondary debuff (Effect): Blind, Bleed, Quiet
Behaviour: Stand still, move vertically, move horizontally, move diagonally, move freely but slower
Shooting pattern: Spray, fixed direction etc like the third boss of shatters
Health: can be a variation within 100k (the boss can be around 300k-400k)
These randomness can be fun to play with and multiple tactic can exist.
