Encoded from the template: DR 5/magic, energy resistance acid/cold/electricity 5, SR 6 (CR 1 + 5). Not encodable in this model: smite evil 2/day (+2 damage vs evil), the bite's free trip on hit (the engine has trip only as a standard-action maneuver, no auto-trip attack qualifier), and the weapon model has no magic property so no equipment bypasses the DR 5/magic (correct for mundane weapons). Summoning scaling (energy resistance +2 and SR +5 per summon spell level above 2nd) is not modeled; this sheet is the summon monster II baseline.",
