I was wondering which monsters I should get. The dragons and starters I am farming and will get soon. I am on Tiamat. This is my team (disregarding levels)
Plasmorex
Luxknight
Shadowlance
Glazio
Pyroviper
Raptorex
Searex
Fireheart
Nilox (replace with a nilomoth?)
Metallodius
Gigaceros
Voltiger
Dullakhan
Stegotops
Skywolf
Mammut
Archeonosis
might be more i forgot to mention (1-3)
edit: such as don Penguini
Get Don penguin I by clicking the tombstone in orlen and write dragon island then evolve it put it at the back then when it is the last one standing use showdown

Plasmorex -> extremely good
Luxknight -> very good
Shadowlance -> very good
Glazio -> replace with a dreadwolf
Pyroviper -> very good
Raptorex -> very good

Gigaceros -> bad
Voltiger -> good
Dullakhan -> bad
Stegotops -> good
Skywolf -> good
Mammut -> bad
Archeonosis .> good
Every 8.5 or more star ark is good. Other very good monsters are Arkwing, Vulcaraptor, Georex, Necrodake, Barricadus, Gremknight, Halopard, Angelon.
im working on a barricadus, angeleon, and georex
Halopard
Its a wonderful healer and def booster and was a staple in my battle with Tiamat.
You can get Halocat near Arborun and it elvlves at Level 35 I believe
Gremknight
Its Stun Skin ability will break a long Bonus Action spam and it is pretty decent with haste
You can get one by fusioning Gremly (Cave of Ages) and Knighthawk (relatively anywhere, mostly in the Haisuna Desert)
how about omegawyrm? for now i already have 3 omega… and currently collecting the 3 dragons to make another 3 omega… is it okay to have 6 of them?
