You’ve battled all of rest, now take on the best. Or at least the one with the highest level. All of your pets should be at least Level 18 before taking her on. Mainly because otherwise you’ll miss way too often and experience frustrating death. Also, if you have a humanoid heavy group, you might want to wait until they’re 19.
The fight is pretty straightforward, but there are a few things to pay attention to.
Jack is a pretty typical elemental. He has Thorns and a Poison Lash ability. He also has an ability called Plant where he plants himself into the ground and after a few turns he uproots and gets a big heal. You can try to time your big attacks around this ability, but it’s not usually necessary.
Put a strong DPS pet on him, avoid using stampede or swarm type abilities because of Thorns, and keep out of reach of Mechanical pets and you should be fine.
Bishibosh is an Undead shaman pet. He has kind of a weird set of abilities. Shadow Slash is your typical Undead attack. Wild Magic does no damage, but puts a debuff on your pet so that it takes extra damage. This can hurt when combined with swarm or flurry type abilities, but fortunately Bishibosh doesn’t have any of those.
Bishibosh also has an ability called Dark Simulacrum. This takes what ever ability you use against him when it is active, and lets him copy it and use it against you every few turns. It’s not really that powerful most of the time, but it is something you should be aware of.
Bishibosh isn’t all that tough unless you are using a dragonkin or humanoid on him. Just DPS him down and use your abilities like normal. He puts enough debuffs on you, however, that you may need to swap your pet out before going after the last member of the team.
Nightstalker is an Undead with life-stealing abilities that make her hard to kill. If you have any pets that do critter damage, save them for her. Her first ability is Plagued Blood. This does some damage and puts a debuff on you that lets her heal herself when she damages you. It can be helpful to put a pet on there to take this debuff and then swap quickly, though it may not be strictly necessary.
She also has an ability called Death Coil. This ability damages you and also heals her for a fair amount. Combined with the Plagued Blood debuff this can be very annoying. Her final ability is Shadow Shock which is a normal Undead damage ability.
The key to beating Nightstalker is to simply damage her faster than she can heal herself. If you have a Critter damaging pet, or a pet with stampede abilities, she isn’t that tough. An Aquatic pet can also do well as it will take less damage.
In summary, this fight can be difficult because of her last pet. If you have a Humanoid heavy composition, you might have alot of trouble. Otherwise, you should be able to get her down after a few tries.
