There, I fixed it(And added a small rotating animation during stand, I will remove it if you don't like it, I just thought it might look kinda cool).
What I did was:
1) Take the bandit missile model, and convert it to MDL.
2) Take your spear mesh and add it on the bandit spear model via Vertex Modifier.
3) Remove the bandit spear mesh and attach the new mesh to the bone "Cone01" via Vertex Modifier,
3) Split the current model into two geosets("duplicate" the geoset) via Notepad.
4) Open whatever came out in Vertex Modifier - remove the spearhead on the first geoset, and remove the spear itself, leaving only the spearhead, on the second geoset via Vertex Modifier.
5) Open the outcome in Magos' Warcraft3 Model Editor, add the two textures - "Textures\CityStructures.blp" and "Textures\CampaignOrcaxe.blp" via the MPQ Browser utility in Magos' Model Editor.
6) Switch the current texture on the only material in the model to "Textures\CityStructures.blp" from "Textures\Bandit.blp" and create a new material, making it use "Textures\CampaignOrcaxe.blp" via Magos.
7) Switch the material on the spearhead geoset to the newly created "CampaignOrcaxe" material via Magos' Model Editor's "Geoset Manager" utility.
8) Create a new geoset animation with the same "Alpha" as the already existing one, and attach that new geoset animation to the spearhead geoset via Magos' Model Editor's "Geoset Animation Manager" utility.
9) Save the model as an ".MDX" file, open it in WarForger and make a small rotating animation in the middle of the "Stand" animation.
And that's it.
