i agree, Wis and Cha look a bit too high. should we really lower them that much though?
To keep it in line with the others, yes.

OK, I’m assuming that we’re working under the assumption of converting this fellow as an age category 4, or juvenile dragon? Therefore, we would be giving it the same categories as a 2E juvenile flame linnorm.
If this is the way the other linnorms appear to have been converted, then yes.

This means, it is immune to fire (automatic with the subtype, of course). Also, it has heat metal, pyrotechnics, and produce fire (all 3/day). If we wanted to give it more than that (judge accordingly by 3E linnorm standards) we also have: fireball (1/3 rounds) as adult, fire charm and fire trap (3/day) as old, flame strike and wall of fire (2/day) as venerable, and fire seeds and firestorm (1/day) as great wyrm.
With the exception of firestorm, none of those spell-likes seems more powerful than what the other 3E linnorms have.

Additionally, they would cast spells probably as a 9th-level sorcerer.
This seems really low. The 13-HD gray linnorm casts as a 17th-level cleric. The others cast at a minimum of 17th level.

For the breath weapons, they would be 8d8+4 or nearest equivalent fire damage. The line of fire is 110-feet long in 2E, and the cloud/cone of ash is 90’ long, 70’ wide, and 40’ deep. Standard dimensions are 120 for line and 60 for cone, which of course are just as good.
8d8 would be about right compared to the other linnorms.

From the MM, page 69, Crush damage would be 4d6+12 (or +18 for 1 ½?) and tail sweep 2d6+12 (or +18?). Suggested damage for the other attacks (we can always use the old values instead) would be: bite 4d6+12, claws 2d8+6, tail slap 2d8+6. if these values seem odd compared to the other linnorms, we can alter as need be.
These values seem fine (compare to Corpse Tearer, another Gargantuan linnorm).

Note that although standard dragons get blindsense 60, FF linnorms get blindsight 120. did the blindsense replace blindsight for standard dragons or is this a thing we can keep?
All dragons have blindsense now, unfortunately. :\
The 3.5 Conversion Guide gave the linnorms blindsense instead as well. (BTW, they're in the MM2

).
