What made them interesting (perhaps only to me) was when they had a swiftness/slow effect on Heat aura (albeit OP).
Without it they are just Fire casting Orcs. I wouldn´t mind seing it return but as a counter give them Naga speed as their default speed and preventing them from moving when hibernating.
If the idea is for them to be more of a hybrid (i.e. Ftr/FE) i think their stat increase should at least yield an equal chance of gaining Str or Int and a bit more variation on skills like
Fig +1, Dgd -1, SpC -2, Cnj +1, Nec +1
Some way to differ Beogh LO´s from Beogh HO would perhaps make them more interesting, like HO could level (or make) melee orc followers more efficient and vice versa.
If LO´s of Beogh then could benefit somehow from their aura would be neat. An example would be giving adjacent followers the Fire Damage Shield and an increase in rF when the LO is heated as well as a decrease in rC when he´s in his “hibernate” state.
The transmuting focus seems odd since there’s so few TrM spells a Lava Orc can benefit from (until higher levels).
If the Transmuting is a given on LOs, maybe introduce a Fire Transmute spell, kinda like an opposite to Ice Form? I know that´s supposedly Dragon Form but that´s a lvl 9 spell. A lvl 2-5 "LavaForm" spell could be interesting to many TrM´s and give Lava Orc´s (and Djinni´s if they ever make it back) an added boost.
//Hey maybe a LO in "Lava Form" could turn into a Djinni haha…
