Dimetrodon Broods

Ebu Gogo has had many broods sired by dimetrodons. These hybrid offspring are a combination of hominid and synapsid features mixed together in manners unusual, unfortunate, unique. Like all their mother's offspring they have inherited something of her forest magicks. 

Groups of half-dimetrodons or specific individuals should be generated through the following stages.

Basic Body Type

1 - Hominid (walks on two legs at a rate of 120, 2 HD)

2 - Dimetrodon (walks on all fours at a rate of 180, 4 HD)

3 - Amalgam (walks awkwardly after extended periods either way, so switches; moves at 90, 3 HD)

Head

1 - Hominid (no advantages)

2 - Dimetrodon (poor eyesight means they are surprised on a 1-4; can bite for 1d6 damage)

3 - Amalgam (can bite for 1d3 danage)

Hands

1 - Hominid (can wield weapons and manipulate objects; if the basic body type is dimetrodon only one-handed melee weapons can be used, at -2 to hit)

2 - Dimetrodon (can scratch for 1d4 damage; if the basic body type is dimetrodon the creature can rear up to scratch)

Tail

1 - Balancing only

2 - Whip tail (can attack for 1d4 damage)

Spine Sail

1 - Small sail (no benefit)

2 - Medium sail (1 in 3 chance that melee or missile attacks hit the sail for only 1 hp damage)

3 - Large sail (1 in 2 chance that melee or missile attacks hit the sail for only 1 hp damage)

Skin Colour

1 - Green (can pass without trace 1/day)

2 - Yellow (can cast confusion 1/day)

3 - Brown (can summon insects 1/day)

4 - Orange (can cast slow 1/day)

5 - Red (can produce fire 1/day)

6 - Unusual (purple, blue, black, white - randomly select or choose a 4th-level druid or magic-user spell)

Sail Colour

The pattern is solid, spotted, swirls, or stripes (roll a d4); this decoration is a paler or darker iteration of the skin colour. 

Dimetrodon hybrids have AC 14. They can use their sail movements to communicate simple concepts at a distance. They resist all heat attacks.
