Why is Zora's Floating Castle the only Mist Generator dungeon that has non-Seru monsters? Because it's not a real Mist Generator!
In the aspect of gameplay, combos that end with "Down" have a high chance of absorbing Seru. Why? Because when you launch something upwards, it may not have the chance of descending to the exact same place where it came from and thus lessens the chance of you easily retrieving it. But when you finish a combo with a downward strike, it will most likely remain in the same place, enough to be easily retrieved.
