Prophet skills of Titan Mission

The first question, just improve the casting speed. I have just met the second difficulty now. The store bought a ring with 12% elemental damage+102% casting speed and a necklace with 13% elemental damage+135% casting speed. I don't know if there is anything better. However, my necklaces are usually installed to improve the level of full skill 1 (because the necklaces also hit the Monkey King).

PS: Personally, I feel that my prophet first put a twisted ripple (1+1,equipment upgrade level 3), and then used a chain lightning (1+full, equipment upgrade level 2), the effect is not much different from that of ice crystals, and it is more magical and can't stop the enemy's rush. Of course, my ice crystal level is not high, and it may not be strong enough. If your ice crystal level is high enough, brush the store, brush the ring of elemental damage and casting speed (I personally brush the hidden store in the second difficulty, and the probability of green is higher).

Second, regarding the shortcut bar, in addition to the following 10 box, there is also 10 box for standby. Press the Y key to switch, and 20 boxes of skills should be enough. It is much more convenient to put all auras and scrolls in the spare quick skill column and common skills in the first skill column. At this time, I also hit the second difficulty. I felt that the skill bar was not enough, and I found myself sweating.
