In the game Silver and Crimson, perhaps many players don't pay special attention to the character Katarina during their daily gameplay. This is mainly because she is of R-rank quality. Compared to those high-quality, high-rarity characters, her initial attributes and abilities may not seem as dazzling. However, one cannot overlook the meticulous design that game designers put into every character.
Although Katarina is of R-rank, she possesses multiple unique skills, which make her invaluable in specific combat scenarios and strategic applications. In terms of her basic attribute settings, her faction belongs to the Church. As a medium-sized character, with a mid-range attack distance, this allows for a fairly flexible choice of output positions on the battlefield. She will not be overly exposed to the enemy's front lines, yet can effectively strike and support the enemy.

Her effect actually lies in recovery, making her a support type character. Her lunar phase setting is New Moon. Regarding Katarina's skills, her normal attack is Incense Burning. In battle, when she performs a normal attack, it can deal 127% of her attack power as magic damage to the main target. The attack power value here is calculated based on her own attributes and possibly some equipment bonuses, etc. This skill damage value is quite considerable among R-rank characters, especially in the early stages of the game or in relatively simple battles.
Besides her normal attack, Katarina also has a very distinctive feature called Censer Guardian. The effect of this feature is closely related to the amount of healing. Its mechanism works such that the lower the percentage of the target's health, the more the healing amount increases, up to a maximum of 50%. This means that in battle, when a teammate's health is low, Katarina's healing of them will receive an additional healing boost. Although this healing effect isn't particularly strong, having both offensive and healing capabilities makes the character quite versatile.

Another important skill of hers is the Combat Skill: Pain-Relieving Incense. This is an actively released skill that triggers once every three normal attacks. When the release conditions are met, this skill will heal the unit with the lowest health percentage by 150% of her attack power. This skill has a very clear direction; it can precisely select the unit with the lowest health for restoration. Moreover, since this skill can be used once every three normal attacks, its frequency is relatively high, allowing Katarina to provide critical healing support to her teammates frequently in battle.

The Ultimate Skill: Incense Curse, when activated in battle, releases a poisonous mist centered around Katarina. The effect of this poisonous mist on the battlefield is very significant. Within the area covered by the poison, it deals 150% of her attack power as magic damage per second to all enemy units within range, and this damage lasts for up to 8 seconds. In team fights or when facing multiple enemies, the continuous damage from the poisonous mist is quite effective. Since the damage is based on a percentage of her attack power, as Katarina's attack power increases, so does the damage from this skill.

Overall, Katarina, as an R-rank character, performs well in the role of support in the game. However, her overall stats still hold a significant advantage compared to other characters of the same quality. If there are higher-quality characters available later on, they can replace her. If you have her, you can use her, but there's no need to invest too many resources in her development.
