To remove animations from skills you simply need to filter out the animation and change it to hit packet.
First scan and cast rising dragon two times on different locations. Now go on the hit packet (the lower one, size 28)
then find another hit packet and compare the beginning of the packet.
Like these for example:
E4 F3 18 00 6D 3C 0B DA AA A5 19 BF A5 81 51 57 27 44 13 E2 B1 80 4F 2F FF 08 D8 F5
E4 F3 18 00 6D 3C 0B DA AA A5 19 BF A5 9A 6A 74 44 61 30 FF CE 9D 6C 6B 3B 46 16 33
As you can see 13 first parts look the same. Copy and paste those somewhere.
Then go to the animation packet, the upper one.
It might look like this:
E2 F1 18 00 6B 3A 09 D8 A8 A3 17 BD A3 98 68 72 42 5F 2E FD CC 9B 6A 7B 4B 60 30 4D
Now make a filter and put 13 first parts from animation packet to the "search" place.
Then take the first 13 parts from hit packet and put them to "modify".
Then just turn the filter on and there, you can instacast rising dragon. This works with every other skill too, you just need to make filter for each skill.
