Here we see a rare origin story for a magic-user. We get a sense that becoming a magic-user is itself dangerous, perhaps even requiring a save vs. poison! In Supplement I: National, I used the snake bite panel to illustrate the Snark Charm spell. The snake may have been charmed into biting Mantoka, although snakes don't always need provocation to bite.
The electric eye trap is our first indication that this is modern day.
Then Mantoka seems to use the spell Stoneskin on himself, unless it's a magical variant of the Super-Tough Skin power.
Mantoka uses a Gaseous Form spell to escape, then uses Burning Hands (even more literal than the D&D version) on the mine guard.
Mantoka gets felled by a head blow.
Being tied up does not hinder his spell-casting, since he seems to have cast Enlargement on himself. Unless, maybe he actually used the wrecking things mechanic on the ropes and enlarging was flavor text.
Mantoka then uses either some new intangibility spell, or maybe an illusion to fool the guards, and then casts a Mass Polymorph spell that turns three men into rats. That's got to be a 6th level spell, meaning Mantoka has ten brevet ranks to cast it! In Supplement I, I used that panel to illustrate the Reincarnate spell, though it does not really match it well.
As illustrated here, movement takes place before combat actions.
We should not be surprised that The Arrow can kill motors and smash guns to bits with his arrows; we have already seen evidence that he should be statted as a superhero, and is using the Wreck at Range power here.
That the Arrow is able to take out a thug (generally 2 HD in H&H) in one punch suggests that he is buffed with the Get Tough power. Hitting four men in one turn suggests he is also buffed with the Flurry of Blows power.
Jinny's response includes the unusual phrase "Not much!" when she means "No way!"
