Ah ok thanks friend, and sorry for the late responseonly have a few mins but short and quick here it is:
the combat skill you need for aron to start the lizard man cow girl sex pose in remcombat is skill number 1613 line 630,
"const SKILL_ENEMY_POSESTART_COWGIRL_LIZARDMAN_ID = 1613;"
so in data/enemies you need to add the line of <AI PoseStart Skills: 1613> like lizardman have to aron. line 210 in data/enemies is aron
i would add in the line n<AI PoseStart Skills: 1613>\n after Petting skills. be sure to use all the correct symbols associated in the script.
this is all for v0.8o . if someone can explain this better please do.
thanks again to mamaboiii for showing me enough js mods to do this mod
