RHD and racial spellcasting progression

[liquidformat]

So for monsters such as Planetar and Solar who have racial spellcasting and progress by increasing RHD does increasing their RHD also increase their spellcasting ability, or should we assume it is fixed unless you gain class levels that would progress spellcasting?

i think by RAW if it doesnt say it increases with RHD it doesnt. But I'd personally probably figure out what fraction of their HD their casting is and have it continue to increase at the same rate as implied by that result.

Indeed. If nothing else is said in the stat sheet, increasing RHD only increases saves, BAB, skills, number of hit points, feats and ability scores if the creature gains a size category. It never advances casting, but most of the time, it can increase the Spell Resistance of the monster, and the DC of (Su) and (Ex) abilities always increases as 1/2 RHD (but the caster level stays the same if it is not stated as scaling with RHD).

As others have said, the general rule is unless it specifically says casting increases with HD (like Nymph Sylph), it does not.

There is an interesting example of a rakshasa advanced by HD with increased casting in one of WotC short online adventures (can't find the link right now), but that's is designer fiat, and an exemption to the rule.

Found it. The adventure is called Tiger's Palace (https://www.drivethrurpg.com/product/181982/Tigers-Palace-30); bearing in mind this is 3.0 material, the rakshasa is advanced to 14HD, and it's sorcerer casting increased to 8th level.

As far as I know, the nymph doesn't say her spellcasting increases when she gains RHD. Where did you find that piece of information?

Oops, I meant Sylph, not Nymph. Always get those two names mixed up.

For some reason I find myself wishing the adventure was called Tiger King :smallbiggrin:

There is RHD increased spellweaver somewhere in magazines and he has increased spellcasting ability.

There is RHD increased spellweaver somewhere in magazines and he has increased spellcasting ability.

It also appears in MM2, along with the above mentioned Sylph.

The Spell Weaver is treated as a sorcerer 2 levels higher than it's HD, while the Sylph is treated as 4 levels higher than its HD.

Just noticed the Sylph wording is a lot less clear than Spell Weaver. The Spell Weaver says "A spell weaver casts spells as a sorcerer two levels higher than its Hit Dice", while the Sylph says "A sylph can cast arcane spells as a sorcerer. Caster level = sylph’s Hit Dice + 4".

Only with regular RHD. In magazine he has increased RHD and increased spellcasting.
