Custom Enemy Woes
When making custom enemies, usually what I do is find a standard enemy that is similar and then research them at paragonwiki.com to see exactly which powers they have. I rarely ever use the presets.
Regardless of their level, Minions typically only have 2 Powers, 1 from their Primary and one from their Secondary. These are almost always lower level powers. In the case of Assault Rifle/Devices, it would probably be Burst and Targeting Drone.
Lieutentants typically have 3 Powers, two of which are usually the same powers as the Minions while the 3rd is a higher level Primary. . . such as Full Auto.
Bosses should ALWAYS be custom, typically having 4 or 5 powers but no more than two being higher level Primary.
Anyways, that's the "system" I use and it seems to work fairly well. Mileage may vary.
I'm having quite some trouble balancing some custom enemies. I've reduced them all to Standard/Standard (or Standard/Hard when it gives them no extra powers) yet they still seem to be far more dangerous than I'd like. I'm not sure whether I'm just choosing especially good sets, but I'll lay them down here to try and find some advice (and to note, although they seem random, that is the nature of the enemy group). The main ones I've been having issues with have been the Minions and Lieutenants.
Minions:
Assault Rifle/Devices
Fiery Melee/Shield Defence
Dual Blades/Poison
Lieutenants:
Electrical Melee/Super Reflexes
War Mace/Willpower
Advice?
Bad Voodoo by @Beyond Reach. Arc ID #373659. Level 20-24. Mr. Bocor has fallen victim to a group of hooded vigilantes who have been plaguing Port Oakes, interfering with illegal operations and pacifying villain's powers. He demands that revenge is taken on these miscreants and his powers are returned! You look like just the villain for the job. Challenging.
