In "Dream New Immortals", Acacia and Immortal are the only two sealing sects, and Acacia, which has the ability to assist seal damage, also has a unique advantage in terms of defense. Moreover, through the Charm Trail, you can also improve the resistance of teammates' seals, which is a very useful ability. With the blessing of the Heavenly Book Skill, Hehuan's seal defense ability will be greatly improved.
The passive skill wing can assist the target of the sad flower, and the double pupil is to increase the sealing hit rate of his current door sealing skill by 10% when the enemy has no sealed target. For Acacia, which has the seal as its main ability, the effect of increasing the sealing rate is significantly greater than that of assisting, so the passive skill is definitely recommended to choose double pupils.
In terms of Acacia's Active Heavenly Book skill, Blossom is a three-time attack on a single target and each time has the probability of exerting a Sad flower effect, which is equivalent to an enhanced version of the Sad Flower. The fallen ying also attacked three times, but the target changed from a single body to a three target. The difference between the two is that the Sadness Flower is cast three times on one goal and the Sadness Flower is cast once on each of the three Goals. Because the selection of sealing targets is often targeted, compared with the scattered and random sealing targets, the more accurate and higher sealing hit rate effect is naturally pursued by Hehuan, so a single skill such as Blossom is a more worthy choice of Tianshu skill.
In summary, the skill recommendation for the Acacia Heavenly Book here is to add a little learning to the smooth flow of double pupils and flowers than the wings falling.
