You could attack from the caverns, if you use a Fused with transformation/cohesion. Distract Jasnah and Shallan, so they can’t impede your progress with transformation, and widen those caverns. If Odium tries this, I suspect that the Coalition would be in serious trouble. The only way they could have a chance would be to unlock/revive the Tower.

I agree with all of these. However, Ba-Ado-Mishram was said to have “Connected with the Parsh people.” Connection is a Bondsmith ability, and Ba-Ado-Mishram “provided the enemy with voidlight.” Dalinar can provide stormlight to his radiants. As for cousinspren, this could actually be a voidspren of some kind, considering the BAM seems to be associated with voidlight and forms of power.
