ok, will change back to "Mad Insight" - just pondering if dndbeyond will be too clunky in statblock format - i.e. I don't think there is any way to put a proviso or footnote in the statblock about substituting CHA for WIS, or is a note in the traits section enough.
Do you prefer option A or B for the
Mad Insight?
Aslo tweaked
Mind Scourge. The chaos savant targets one creature within 60 feet, who takes 10 (3d6) psychic damage, and must make a DC 16 Intelligence saving throw or choose to be stunned or take a further 10 (3d6) psychic damage the next turn.
Hmm, I'd prefer…
Mind Scourge. The chaos savant targets one creature within 60 feet, who takes 10 (3d6) psychic damage and must make a DC 15 Intelligence saving throw. If the save fails, then at the start of the target's next turn it must choose between taking an additional further 10 (3d6) psychic damage or being stunned until the end of their turn.
A bit wordier but clearer.
For
Strength of Madness, I was thinking of taking a different approach, like so:
Strength of Madness (Recharges After Short Rest.). Until the end of the chaos savant's turn, all the savant's melee attacks have advantage on rolls to hit and inflict an additional # (#d#) damage.
That's seems more in keeping with the original version.
We'll need to decide how much the bonus damage is. I was thinking maybe 3 (1d6), 5 (2d4) or 7 (2d6) but it partially depends on the frequency.
If you want to make it
Recharge 4-6 I'd recommend giving it a lower damage boost than if it was
Recharge After a Short Rest since it'll add the possibility of it kicking off multiple times.
Don't care as much for the proposal above, since (a) it doesn't have a duration stated. Is it only for the next attacks? Every attack during the encounter? and (b) doubling the modifier for to hit and damage feels too "swingey" as it could either be overpowered (if it's CHA-based that's +8 to hit and damage instead of +4) or worse than useless (if it's using a regular STR-based weapon as its STR modifier is negative 1!).
