Naix CFG [Need Help]

Hi guys, I need help please with the cfg file for naix hero.

I am trying to make naix script that when I use his third skill (slow/open wounds) to a hero, It will attack that unit, and not change attack when there is enemy unit NEARER it choose to attack it instead of the unit I spell with third skill. (Hope u understand). Thats the first one I want to achieve, The second one is that, when I use Third Skill, it will auto activates the Armlet of Mordiggan along with using the third skill? I've been trying but failed.

Here's the one I made. (This script fails both mission) lol

bind "e" "dota_item_execute 0;dota_player_units_auto_attack 0;mc_attack"


Ive found this code.

// Use the alias "smartcast" after any item command to make it trigger instantly. For example: bind "mouse5" "dota_item_execute 0;smartcast;" alias "smartcast" "+sixense_left_click;-sixense_left_click;"

so can any1 help me how can I use this smartcast? I tried making
bind "e" "dota_player_units_auto_attack 0;mc_attack;smartcast"

but still dint auto activates the Armlet after I use thirdskill. and it still doesnt chase the clicked unit. it auto changes attack to NEARER enemy.

Any suggestions, comments anything that can help the topic Please Post.

Thanks.
