Event's story was decent, if a little repetitive. One of those charming events with nice interactions. It would've been on par with this year's serpent event or better had the ending not been a wet fart.
Doesn't make sense to start the event with Arjuna's begrudging relationship with Vritra, complete with its own CG, develop it, and then walk back on everything at the last second to settle on Vritra as an abrupt twist villain.
Setting up Indra's flaws as a pompous braggart and an absentee father towards and Arjuna's implicit wariness towards him, but never writing the confrontation about it between the two really sours me too.
Felt like they were building into something at first but the finale is a really dire narrative backfire that spoils the rest of the experience.

The first challenge is Bhima, infused with the sky's wind. Indra summoned him and the other Servants from Chaldea.
Inside Bhima's field, the strong wind causes Vritra to fly away again, but she’s saved by grabbing hold of Rama's banana.
Bhima's wind prevents us from laying a hand on him, so, inspired by Vritra's activities in the Mystic Eyes Symphony event, we build a very big blow gun and fire Arjuna like an arrow with enough speed to pierce Bhima's wind and defeat him.
Rama, Arjuna, and (You) fist bump, but Arjuna refuses to fist bump Vritra because she's an evil dragon. The two compromise and touch fingers. It reminds (You) of a scene from an old movie.
Indra's not impressed by us, but on the brightside, Bhima's accompanying us to the next Trial.
