Converting old school DnD to Simple d100 Fantasy

I've been eyeing the excellent Arden Vul mega dungeon lately, thinking of starting an open table of sorts for a weekly game, using Old School Essentials BASIC rules for it. And then I got thinking - can Simple d100 Fantasy be used for a mega-dungeon? I dont know, yet. I will have to try it. But what I discovered at least was that converting between the two systems is very easy. 

Please download and have a look at the coversion document at this point, and then have a look at the excellent Tomb of the Serpent kings adventure for old DnD types. Here are my Simple d100 Fantasy versions of the monsters contained within said tomb:

Black pudding

Armour 6, Guard 50, ATT 1x touch 70% +15Dmg, MV 6 m/round, Resillience 20.

Mummy fragments

Armour 0, Guard 10, ATT 1x brawl 30% +0Dmg, Mv 6 m/r, Resillience 10

Stone cobra guardian

Armour 11, Guard 30, ATT 2x sword 50% +6 or 1x Slam 40% +2Dmg to adjacent or 1x Shield draw 30% +4Dmg in a line from the shield to the statue, Mv 10 m/r, Resillience 20

Succubus

Armour 11, Guard 40, ATT ?, Mv 10 m/r, teleport 3m, Resillience ?

Skeleton

Armour 2, Guard 5, ATT 1x weapon 30% +4Dmg, MV 6 m/round, Resillience 10

Skeleton jellies

Armour 2, Guard infinite, ATT 1x grappling 30% +2Dmg, Mv 5 m/round, Resillience infinite

Fungus goblins

Armour 6, Guard 5, ATT 1x weapon 30% +2Dmg, Mv 6 m/round, Resillience 5

Xiximanter

Armour 11, Guard 50, ATT 1x fangs 70% +2Dmg, Mv 6 m/round, Resillience 50

Immune to spells 50%, Casts all sorts of spells at 80%

Basilisk

Armour 11, Guard 35, ATT 1x Charge 60% +5Dmg or 1x Lizard frenzy 50% +2Dmg to adjacent or 1x Tail strike 40% +5Dmg, Mv 6 m/round, Resillience 20

Stare Will test or be petrified.

This was a simple conversion, it didn't take me long at all to do. Old school DnD is excellent in this way - no funny business, monster stats are a few lines of text and done. The game is in the playing, not in stats and frills, just like Simple d100 Fantasy I would argue.

Anyway, off with you to test out Keep on the Borderlands with Simple d100 Fantasy now!
