Gnasher and drask lose like 90% of it and chornovore and thrax lose only the tippety tip. That's surprisingly little since their tails are so large.
Also making gnasher lose his tail to stop him from slapping is making the fight deeper. I would love to cut off more of the chronovore's tail to stop him from whipping everyone in front of it.
External link →Every Behemoth is a little different. There's no one size fits all and things have changed.
Depending on when and how a Behemoth was designed, a sever can occasionally disable/change its moves, but not for every single one. A lot of the time, severing too far up the tail would make a ton of moves useless, mess up the silhouette.
It's pretty case by case at this point.
