Strange is correct! Stephanivien has manufactured (and placed) several Ballista-style firing armaments that can be modified to throw either harpoon/spear-style bolts or magically modified bolas in the interest of capturing/subduing Irenia or killing her, if it comes to that. Bolas should be made/modified so that Stephen Strange (or someone else very magically inclined) can juice them up to enlarged size once fired to be able to wrap around her jaws.

Basically if its canonball-ish or bolt/spear-ish it can be spring-loaded and fired. Probably should not be used to projectile throw people, but if someone is dumb enough to try with it it's probably theoretically possible.

He will be up and around to help with maintenance and repair, instructing people how to fire, etc. as well as his own magic revolver to deal with harpies/other flying/attacking enemies
