Adding Dragon Tail / Viper Fang to 5165 client?

Hello community,

I've been trying to find a way to get Dragon Tail / Viper Fang on a 5165 client but for some reason after adding it, all skills lose effects, attacks no longer display damage to monsters, all i see is some green lines appearing shortly with no character animation whenever I use the skills.

On server side I just added the new ids similar to SS/FB so I can learn & use them.

What I did on client side
1. Added skill in ini/MagicType.dat
2. Modified ani/Magic.ini to specify location of skills icons
3. Added data/main/.dds files for the skill icons
4. Added required files ini/tme/longpi* and longci* files
5. Added required files c3/effect/other/longpi* and longci* c3 & dds files & c3/effect/skill/tempest/ c3 & dds files
6. Extracted ini/c3.wdb so i got the dbc files for 3DEffect, 3DEffectObj, 3dtexture
Converted dbc files to txt and added the relevant [longci*] / [longpi*] sections into 3DEffect.txt, packed back to dbc
In 3DEffectObj.txt added the relevant mapping between effect id and c3 files eg. 15409=c3/effect/other/longci4_453/1.c3 , packed back to dbc
In 3dtexture.txt added the relevant mapping between texture id and dds files eg. 15409=c3/effect/other/longci4_453/1.dds , packed back to dbc

Then I moved the 3 dbc files back to the ini/ folder and started the client.

Could anyone tell me if I am doing something wrong or if I am missing an additional step? Much appreciated.

I've successfully added it to a 5071 client, but there are 3 things you may be missing:
- The ini/MagicType.dat has a different format, make sure to adjust to your client version
- These new magic skills are using new motions (otherwise the character won't move properly)
- Part of the Viper Fang effects (i.e. the C3 files) are using features that are unsupported in older clients, I had to tweak these C3 files

Well copying the ini/c3.wdb from another client where the skills are already implemented seem to make the "skill effect" show without breaking the other skills, but the character itself has no animation, but once again this bring some extra NPC effects such as Exclamation marks above the NPCs which I would like to avoid, so I am not sure what is causing the effects to fall apart when touching just the 3 files 3DEffect, 3DEffectObj, 3dtexture. And on top of that not sure what is responsible for showing the character animation properly when casting these skills. Any chance you could highlight where to look into?
