Death from above! (Maybe...)
The Spider is an enemy that can be encountered in the Ishlith Shrine in Momodora III.
It appears only in one place in the game, almost right at the start over the Fairy Bottle. It works more like a trap, since the player is likely to run right to the item and gets punished for that by the spider.
The spider takes three hits to die and will start to swing back and forth after being hit, which might allow it to get another hit in.
