//===== rAthena Script =======================================

//===== Description: =========================================
//= [Walkthrough Conversion]
//= Wave Mode Forest and Sky Instances
//- Officially monsters can use their skills
//    (NPC_SUMMONSLAVE, at least). NPC_EMOTION and
//    NPC_EMOTION_ON have been blocked since it disrupts the
//    walk system of the instance on rAthena.
//- Note: The instance is currently disabled on KRO.
//===== Changelogs: ==========================================
//= 1.0 First version. [Capuche]
//============================================================

// Move the monster to the next coordinates + end the script on successful; kill the monster + return on failure
