This is the HD naga male base model from World of Warcraft in 6 colors, ported by me. It is meant to have a weapon attached, and I've animated it so that you can give it your choice of:
-the traditional two-handed polearm (base animations)
-a one-handed weapon and shield, or two one-handed weapons (Alternate animations)
-a javelin/harpoon/throwable spear (Upgrade animations)
It has Swim animations for standing, walking, attacking, and dying. I didn't include Swim animations for all the spells it has because that would be too much. I recommend having it play attack animations when casting spells in the water.
I also posted a team-color version
in a separate pack. I personally find the team color solution I finally settled upon to be a bit ugly, but some may want it anyway.
Feel free to give it attachments (weapons, team-colored shoulderpads, etc.) and create new models out of this.
