I've had an idea for my group to encounter versions of them selves; they are in the middle of a battle with undead versions as we speak!
I'll own up to inspiration from the web comic Goblins...
One of my ideas is to have a group of half green dragons. They managed to avoid a recent battle with a green dragon, and it would be cool that the dragon sets his children onto the party!
The party themselves are 8th level, with their first, recently acquired Mythic level and are v. tough! Elven male Life Oracle, Human male Barbarian, Dwarven female Fighter, Dwarven male Arcanist and Drow male Rogue/Ranger.
So what I could do with is a human, two dwarves (one male, one female), an elf and a drow - apart from the one dwarf, all are male. All to have the half green dragon template, and therefore be each a total of CR 8-10...
...any class is acceptable, any 3pp, as long as it is on the prd/d20pfsrd sites. They only need NPC kit. I've already done a version of the party that takes advantage of teamwork feats (paired opp, outflank, stealth synergy, etc) so you don't have to bother with that...but other group strategies are welcome! Things that might throw my players for a couple of rounds at least...
Gratitude in advance!
