DOCTRINE
Use slides to approach from outside the bishop's diagonal squares, and build dagger pressure while Solomon is exposed. Leave enough room to turn before a rook hits instead of assuming sliding will carry you through immobilize.
Use Petrifying Bola on Solomon when teammates can attack as petrify ends. Lethal Venom can damage him during petrify; save ordinary attacks until he becomes vulnerable again.
Attack from another side of the queen's marked area and keep an exit for the next move. Your slide barrier can help a trade, but it does not justify staying in repeated attacks once your health becomes low.
