Were Dex modifiers for AC ever a part of OD&D? I like them, just one more thing from Iron Falcon I am incorporating to my campaign, but it got me to wondering if they had been added to OD&D in a supplement that I am not remembering seeing.

On the 6th level Magic-User spell list, four spells are missing (they are included in the spell descriptions, just not on the master list on page 21). Any chance of getting a revised PDF with the list updated?

Missing 6th level spells:

Stone to Flesh
Reincarnation
Projected Image
Repulsion

Thanks!

I'm curious about the large difference in XP numbers for level progression compared to OD&D. What was the reason for such higher numbers (a 10th level Magic-User in OD&D is 200,000 xp, but in Iron Falcon it is 600,000 xp)?
