As of June 3rd, the specialeffect() command has been upgraded and it now allows to use effects on any kind of unit (player, npc, mob, homunculus, ...) and to show it to any player. This allowed us to deprecate specialeffect2() and misceffect() so now there is a single command for effects instead of 3 different ones, making things simpler for everyone. You can still use specialeffect2() and misceffect() but they will trigger a warning every time, since they will be removed in the future.
