Anyhow, it looks like we have enough to update the
Foxdragon Working Draft.
I've put the following in the Working Draft as rough drafts for the two special abilities we've thought of so far:
Burn (Ex): A foxdragon's tail attack deals bludgeoning damage plus fire damage from the creature's fiery tail. Those hit by a foxdragon's tail attack also must succeed on a DC X Reflex save or catch on fire. The flame burns for 1d4 rounds. A burning creature can take a move action to put out the flame. The save DC is Constitution-based.
Heat Haze (Ex): A foxdragon can heat the air surrounding it to bend and blur light, making it difficult to surmise the creature's true location. Any melee or ranged attack directed at it has a 20% miss chance unless the attacker can locate the beast by some means other than sight. A
see invisibility spell does not counteract this effect, but a
true seeing allows the user to see the foxdragon's position.
We've got a couple of important questions to settle next.
How many Hit Dice do we give it? I'm thinking 2 Hit Dice like a Pseudodragon rather than 1 HD like a Fox.
Land speed 40 ft. like a Fox, plus fly 60 ft. (good) like a Pseudodragon? I reckon this thing ought to have supernatural flight - that's a common ability for "Oriental" type D&D dragons.
What damage for the bite and tail. 1d4 for the bite (like a Fox) and 1d3 for the tail (like a Pseudodragon's sting) plus either 1d4 fire (like a Small Fire Elemental) or 1d3 fire (the "next size down" from a Small Fire Elemental's damage)?
