The idea of predators is the place where Army Ants as a concept diverges markedly from a traditional military RPG. There are big monsters in the natural world that want to eat you!
Rather than having the dice continue to scale beyond D20 (which I’m not a big fan of), this is going to be much simpler:
- A Large creature (considerably larger than the ants and their ilk) adds another die of the same type when rolling damage and hits. Such a creature is considered 5 levels higher than its level would be otherwise. A Large creature takes +1 to all Feat rolls beyond its actual level.
- A Huge creature (far beyond the scale of an ant) adds two dice of the same type when rolling damage and hits. Such a creature is considered 10 levels higher than its level would be otherwise. A Huge creature takes +2 to all Feat rolls beyond its actual level.
This means that a chameleon (as a for instance) might have Body D12. A standard chameleon rolls D12 for its hits and for its melee damage; a Large chameleon rolls 2D12 for its hits and melee damage; a Huge chameleon rolls 3D12 for its hits and damage. This keeps the resistant rolls from scaling beyond the ants’ abilities to hit or deal damage. You use the same fundamental build for creatures of different scales… Here’s a work through for a Chameleon:
Chameleon (43 CPs, Level 7)
Body D12; Prowess D10; Spirit D10
Bite +5; Melee +4; Stealth +4
A small chameleon has an average of 46 hits; it rolls D12+5 for bite damage; it has a Feat bonus of +4; it is considered Level 7.
A large chameleon has an average of 91 hits; it rolls 2D12+5 for bite damage; it has a Feat bonus of +5; it is considered Level 12.
A huge chameleon has an average of 137 hits; it rolls 3D12+5 for bite damage; it has a Feat bonus of +6; it is considered Level 17.
FYI, this is the new structure for determining levels based on CP totals:
0 to 3 CPs = level 0
4 to 9 CPs = level 1
10 to 15 CPs = level 2
16 to 21 CPs = level 3
22 to 27 CPs = level 4
28 to 33 CPs = level 5
34 to 39 CPs = level 6
40 to 45 CPs = level 7
46 to 51 CPs = level 8
52 to 57 CPs = level 9
58 to 63 CPs = level 10
64 to 69 CPs = level 11
70 to 75 CPs = level 12
