So I want to throw a few Tyranid creatures at a Deathwatch team that are not currently available in rulebooks. Specifically, I was looking to have a climactic battle against a Tervigon and swarms of lesser Tyranid and wanted to get your opinions regarding its overall power and abilities. I have created a profile using preexisting rules and traits as well as new powers derived from the Warhammer 40,000 Tyranid 5th Edition codex:
This is a quick mockup and I'm sure there are mistakes/typos in there that will need to be corrected. My concern currently is if this looks viable and not overpowered/underpowered. Essentially the statline is the Hive Tyrant with its combat skills and speed reduced and its overall toughness increased. I would appreciate any input you may have with this creature.
