"She is dangerous," the witch cautioned him.
"And beyond me," Mostin nodded.
Mulissu laughed. "Maybe, in a straight fight. But I’m assuming you’d cheat. What’s the biggest evocation you can deliver?"
"Against a Cambion? Sonically Substituted Maximized Empowered Lightning Bolt."
Still, the plan was to blast Feezuu with many sonics."What spells did you have in mind to ‘whack her’ with," Nwm inquired.
"Quickened ‘Magic Missile’, ‘Disintegrate’, and ‘Great Shout’. If we’re hasted, and we get the jump, I can get them all off before she can react. Ortwin zaps her with my ‘Circlet of Blasting.’ If she’s still standing, she’ll probably be stunned from the sonic – as will at least some of her cronies. That’s when Ortwin finishes her off. If he takes longer than five seconds then, a) I’ll be disappointed in him and, b) I’ll whack her with two sonically substituted maximized ‘Lightning Bolts’ and another quickened ‘Magic Missile’. If that doesn’t finish her off, then I’m changing my vocation."
Why did Mostin attack Ainhorr with his spells, instead of Feezuu? Wasn't the idea to "whatck" Feezuu? And Mostin must have known that a balor would shrug off his spells while the cambion might not have.Mostin swallowed and knew that if he attracted attention, would probably be next. Oh, well, he thought. He let loose his "Great Shout" and flung a quickened "Magic Missile" followed by "Disintegrate" at the Balor. The sonic blew a hole in the magically sustained blood walls, and several Slaadi stopped in their tracks. Feezuu was staggered. Ainhorr brushed off all of the spells, his concentration unaffected.
Again, Mostin used spells on Ainhorr instead of Feezuu. Apparently, though, Feezuu took enough collateral damage from the sonics to render her vulnerable to Mostin's final attack:Mostin smiled and let loose two more potent Sonics at point-blank range and hurled another quickened packet of "Magic Missiles" at the Balor. Summoned Devils and Slaadi alike exploded under the force of sound. Feezuu reeled: she was in trouble.
Well. As we know, she wasn't really dead. But she might have been if Mostin had consistently targeted Feezuu.Sh*t, thought Mostin, and fired off his last sonic attack and quickened "Magic Missile" at Feezuu. The Necromancer finally crumpled under Mostin’s power.
Yes, that's right. But:Jeremy said:As I recall Ainhorr's prescence at the time was an inconvenient coincidence
Why? Mostin's spells wouldn't even scratch a balor, so why did he bother casting them on Ainhorr? If Mostin had focused all his energies on Feezuu (ignoring Ainhorr), he might've finished her off then and there. If your goal is to "whack" someone, 'port in and whack her, ignoring everyone else. That's all I'm saying.and caused a shift in priorities to help ensure survival.
