So if i used a team base to Work Together, could inuse the power action to use "Solo Adventurer" to then use that character.

Ex. Villians for hire, at full, use working together. They move up into hindering. The opponent barriers their troops. As their power action, could they use solo adventurer to deploy cinder to melt the blocking terrain. Then to use their net 3 actions on ranged attacks?

If you use Working Together you could use the Power Action for Solo Adventure, but you could not give that character any actions until all actions resolve from Working Together.

Yes you can use working together to pop off a team member. However note that you must finnish the "Working together" completely before the removed team member can act.

Which means that it won't work. The team base is forced to use the remaining free actions before Cinder can use her special Phasing/Teleport power.

Thanks! That stinks.
