Thanks, this helps a lot.
I find this off a google search:
<npcDefinition>
<id>3494</id>
<name>flambeed</name>
<examine>steroids much?</examine>
<respawn>60</respawn>
<combat>149</combat>
<hitpoints>500</hitpoints>
<maxHit>30</maxHit>
<attackSpeed>5</attackSpeed>
<attackAnim>11402</attackAnim>
<defenceAnim>11401</defenceAnim>
<deathAnim>11400</deathAnim>
</npcDefinition>

I wonder if pasting that but updating the npc id will fix it? Or does the animation have to be coded in the server or something? I'll try it, can't hurt. If it doesn't work I will just revert it.
