Listing possible skills and passives for Douma and his cryokinesis demon art.
Remembering that it is based on the combat style and I also do not have some knowledge of the game, just from the outside.
Possible Passives
1 - Icy Resilience
Description - The user moves faster in cold biomes and does not suffer movement penalties in icy terrain.
2 - Glacial Connection
Description - The user recovers faster in cold biomes and is more resistant to debuffs while in these environments.
3 - Frosty Midas Touch
Description - Every weapon the user uses, such as warfans or other demon swords, has a 0.3% chance with each attack of causing the freezing effect.
4 - Cold Lungs
Description - It has the power that when a slayer is hit by its ice attack, it slows down its breathing due to the ice.
Possible Active Skills
1 - Shattered Ice
Description - The user launches an ice ball that, when colliding with the ground or enemy, causes an initial explosion and fragments into dozens of shards that ricochet around the environment, causing damage and bleed.
2 - Frost Illusion
Description - Creates illusory ice clones that imitate the user, confusing enemies. The clones attack and move like the user, but do not cause damage due to the reason that if they did due to the game's combat it would be very op.
3 - Icy Impact Chain
Description - The user creates chains of ice that connect to the target and allow them to pull the target and punch them for damage.
4 - Freezing Claws: Ice Lotus Sequence
Description - The user creates sharp ice claws on their hands and launches a quick sequence of 8 attacks showing the trails of the ice attacks.
5 - Pillars of Ice: Lotus Rise
Description - The user summons pillars of ice that sprout from the ground, forming something like a frozen lotus garden. These pillars deal damage when they rise and then shatter, scattering chunks of ice that hit nearby enemies.
