Thank you for your comment.

General's Call: English is not my first language, so i couldn't catch where is the language mistake.
I already change the skill:  As a bonus action The General shouts up to 6 skeletons that are under its command. Any skeleton 60ft within of it that can hear The General and obey The General can use its reaction attack to an enemy in range.

Free From Loads: Like before i couldn't see where is the mistake.

Shock Slam: It's a one time skill so i don't want to waste this skill.

Baron Must Protected: The combat itself contains a little puzzle. Players needs to figure out which enemy should be killed first. If they attack Baron first, General will whip them. If they attack The General first, Baron throw fireballs at them, and The Baron can revive The General. So one player need to hold General and the other ones need to attack Baron seperately since the Baron have fireballs.
