Sure, I could make the thousand armed god/monstrosity of death and dismemberment... but that isn't that flavorful at all. I've decided to go with a somewhat old classic, the Wyvern. It is my first time really sitting down to work on a long term build for an Eidolon, so any assistance would be wonderful. (Note, I have looked at Saph's Summoner's Guide)
For those who don't know of the Wyvern, its similar to a dragon, but often is depicted with fewer legs. This said, there's many different variations of wyverns, some with 2 legs, others with none, some capable of breath attacks, others with a venomous bite, and even a sea-wyvern, that instead of a spiked tail, has a webbed tail similar to that of a fish.
With all of this said though, I was trying to figure out what would be best for evolving this wyvern over time through the evolution points. So far I had come up with the following:
Base form - Serpentine
Free Evolutions, Bite, climb, reach (bite), tail, tail slap
Level 1(3): Improved Natural ArmorX1(1), Limbs(legs)(2)
Level 2(4): Improved Natural ArmorX1(1), Limbs(legs)(2), Improved Damage(bite)(1)
Level 3(5): Improved Natural ArmorX1(1), Limbs(legs)(2), Improved Damage(bite)(1), Improved Damage(tail slap)(1)
Level 4(7): Improved Natural ArmorX1(1), Limbs(legs)(2), Claws(1), Flight(3)
Level 5(8): Improved Natural ArmorX2(2), Limbs(legs(2), Claws(1), Flight(3)
Level 6(9): Improved Natural ArmorX2(2), Limbs(legs(2), Claws(1), Flight(3), Improved Damage(claws)(1)
Level 7(10): Improved Natural ArmorX2(2), Limbs(legs(2), Claws(1), Flight(3), Improved Damage(claws)(1), Skilled(Fly)(1)
Level 8(11): Improved Natural ArmorX2(2), Limbs(legs)(2), Claws(1), Flight(3), Improved Damage(claws)(1), Skilled(Fly)(1), Improved Damage(Bite)(1)
Level 9(13): Large(4), Improved Natural ArmorX2(2), Limbs(Legs)(2), Claws(1), Flight(3), Improved Damage(claws)(1)
Level 10(14): Large(4), Improved Natural ArmorX3(3), Limbs(Legs)(2), Claws(1), Flight(3), Improved Damage(claws)(1)
Level 11(15): Large(4), Improved Natural ArmorX3(3), Limbs(Legs)(2), Claws(1), Flight(3), Gore(2)
Level 12(16): Large(4), Improved Natural ArmorX3(3), Limbs(Legs)(2), Claws(1), Flight(3), Gore(2), Mount(1)
Level 13(17): Large(4), Improved Natural ArmorX3(3), Limbs(Legs)(2), Claws(1), Flight(3), Gore(2), Mount(1), Skilled(fly)(1)
Level 14(19): Large(4), Improved Natural ArmorX3(3), Limbs(Legs)(2), Claws(1), Flight(3), Wing Buffet(1), Mount(1), Skilled(fly)(1), Frightful Appearance(3)
Level 15(20): Large(4), Improved Natural ArmorX4(4), Limbs(Legs)(2), Claws(1), Flight(3), Wing Buffet(1), Mount(1), Skilled(fly)(1), Frightful Appearance(3)
Things I have been debating about is whether I should get grab and swallow whole, or whether or not to initially start with the aquatic form instead of the serpentine. Also I have been wondering whether or not the current build would contribute enough to the team as a whole. Any feedback would be greatly appreciated.
