No Thunderbolt because our Mage is in combat, it's a Magic Missle.
So that leaves us Comet, Shard, Harmonic and Prayers. Figures, the one time magic is irrelevant is the turn we get +4 Magic dice.
The only thing that's tight is the Hydra fight, the Tank and Demigryphs out west are gone. So shard on the Hydra and Harmonic on the Demigryphs.
How do we get there? Not even sure it's worth a miscast, so just load up on prayers early?
