Heroic deeds, spells, and experience

Steady progress is being made in developing the Scarlet Horizons setting and rules. I'm up to thirty-eight Heroic Deeds and five spells. I have sixteen character classes — four of them core classes, the others subclasses of one of the core classes.

Eleven character classes are at least marginally complete, and five others need my attention. In the rules I'm creating, I'm incentivizing multi-classing in a number of ways, and in some limited ways creating a disincentive: what long-term player wouldn't eventually want his PC to take 20+ levels in the Fighter core class, given the bonus hit point those levels offer?

It's now been three days since I did any work on furthering the escapades of Matthias d'Slaytonthorpe — scholar-mage and his cleric-mystic fellow Seeker — Aurioch 'Aury' d'Rosenberg.

It's all well and good to develop the Scarlet Horizons setting and rules, but I don't want to miss out on the actual game play. Our heroes have, after all, only recently survived an ambush by froglings in the bog southwest of Helix, near The Blackened Forest.

I'm going to have to figure out a way to convert defeated monsters and treasure into Experience. Matthias and Aury need a total of 2.0 Exp to attain 2nd level. Let's consider possible ways to translate defeated monsters into Exp.

Warning: spit-balling section below:

As a starting point, let's say that for each HD that a defeated monster possessed, we'll assign a starting fraction of 0.001; if the monster had any special resistances, we'd add 0.00025. And perhaps for each attack per round beyond one, we add 0.001.

If the monster was particularly weak or mediocre, subtract 0.00025.

Armor class below 7? Add 0.00010; below 4? Add another 0.00010. Below 1? Add 0.00015.

What does this give us in composite for a single frogling?

0.001 (per Hit Die)
subtract 0.00025 (weak vs robust creature HP/saves)
AC 6 (add 0.00010)
Special ability 'Jump' (add 0.00015)
Attacked as part of a group (add 0.00015)
PC(s) harmed by monster or compatriots at least once (add 0.00015)

This yields 0.0013. Multiplied times ten froglings: 0.013.

I did land on Fractional Experience values for defeated froglings.
