It doesn't get more old school than this
Sometimes, Wizards send out something that’s so ass-kickingly good, I’ll forgive them almost anything.
In Start Here (free-to-view, no subscription required), Bart Carroll takes a look at D&D Starter Sets through the ages, and provides us not only with PDFs of the original dungeons from the 1977 (Blue Book) and 1983 (Red Book), but also 4e stats for Bargle himself. I can hear you old-schoolers weeping with joy right now; oh yes I can. Don’t hold it back…… there there…….
Bargle’s statblock has – get this – real, honest-to-goodness old-school spells including Magic Missile, Fireball, Charm Person and Hold Person. I can see these being stolen and used as templates for further spell conversions for time to come. Lovely stuff.
All of this reinforces my impression that 4e is the new old-school. Oh yeh! Now I’ve just got to convince some players to let me run them through the original Starter Dungeons, 4e style!
