- Change Vortex boss mechanics. For example Vortex boss can loss it's hp throughout the season and got less than half hp at the mid of the season. It means Rook passive won't work and his damage will be lower
- Make Rook less important:
2.1 Rook is not good at other game mods especially in arena so giving clepsydra at arena will help. Other heroes and exclusives will shine there and became important
2.2 You also can implement new game modes where players can earn clepsydra and where Rook not that great (new rage mod didnt work). For example: Rook not that good at fast runs. Other exclusives can burst bosses (from dungeons) and run dungeon floors (domains) faster. We already got that compete element in the game, just expand it. - Buff other exclusives/their artifacts or mechanics. Just balance them that way they can compete somehow. Atleast their awakened versions (add the cumulative effect to the damage or boost to the damage if the target alone (it works well with Orfenna))
