OK, so I am getting a campaign book together for my Pathfinder world and wanted to use an initiative system I used to use in D&D 3.0/3.5 but my external drive crashed some time ago, taking many of my digital notes with it. I found pieces of it, but wanted to try and find it again or modify it a bit on my own so it works in my world. Yes, this system appears clunky, but I have found it work out just fine for the most part but even I am open to suggestions.
This works for melee and ranged right now but is missing the magic end of things and more than likely could use some work (especially with the release of Unchanined).
Here is the part I found after a great deal of searching today:
FreeGamers' Initiative (For use with 3.x D&D):
Base Initiative (BI) = Dexterity + Int Mod + Size Mod + Wpn Mod + Armor Mod
Combat Initiative = Base Initiative + d10
Size:
Fine: +8
Diminutive: +6
Tiny: +4
Small: +2
Medium: -
Large: -2
Huge: -4
Gargantuan: -6
Colossal: -8
Weapon:
Unarmed / Natural: +3
Light Weapon, Dart, Shuriken: +2
1 Handed, Bows, Light X-Bow: -
2H Melee, Over-Sized 1H, Hvy X-Bow, Javelin, Net: -2
Over-Sized 2H, Siege Equipment: -5
Armor Modifier: 1/2 the Armor Check Penlaty of Armor & Shield (Round up)
Examples:
A Human Paladin wearing Full Plate & Heavy Shield w/ Longsword. He's got a 12 Int and 14 Dex. His BI would be 14 (Dex) +1 (Int) +0 (Size), +0 (Weapon) -4 (Half Total Armor Check Penalty) = 11 BI.
His Combat Inititative would be 11 +d10, or a range of 12 - 21.
Now take an Elven Monk fighting bare-handed w/o armor. He's got a 16 Dex and 10 Int. His BI is 16 + 0 + 0 + 3 + 0 = 19.
His Combat Initiative would be 19 +d10, or a range of 20 - 29.
There is literally a 1% chance the Paladin would go before the Monk, and a 2% chance they would act simultaneously - barring initiative enhancements, alternative armors, ability enhancements, etc... In a normal d20 Init system like D&D has the Paladin would actually act first 40% of the time - which is basically just flat-out random and doesn't properly reflect one's weapons and armor being used as a means of being slower to act.
Any help on this will be greatly appreciated.
