Swarm that walks crusade choices unclear.

[Arisu]

So, having reached the point of being a swarm that walks in act 5, I've had a few groups of cultists ask to join me. They gave some crusade mode choices, but one of the choices was something for the commander. So far one of them was a feat "Sting of the swarm" that should give 2d6 sneak attack. Another was supposed to give the ability to cast some spells. Since I play with crusade mode off, I picked the option for the commander abilities, but neither of these seem to work. Am I misunderstanding how they are supposed to work? Are they crusade mode only?

All of the Path choices you make from the war council room affect the Crusade Mode system. When you become a SWARM, your former generals are replaced with an insect clone of your commander.

The choices would have given your general some new abilities, such as summoning a swarm of insects to add to their army, or making your units better at flanking the enemy armies in battle.

Since you disabled crusade mode, these events are useless to you. You don't get any benefit from them.
