I can see two ways of balancing dwarfism, one serious and one slightly tongue in cheek
Firstly, sata obviously heals on a fixed repetative percentage chance.
If this were changed so that the percentage chance increased with each sata then
an element of randomness could be retained whilst limiting the maximum sata that could
ever be required. E. G. 33% chance increasing would give mean that 4 sata would always cure
dwarfism, 33% on first 66% on second 99% on third and over 100% on fourth.
This would not reduce the potion to an instantly triggerable effect but would curb the
ludicrous sata ingestion that sometimes has to occur to heal it.
Secondly. the playing field could be balanced by putting splashing back into scholarship
and seeing how far a skill its supporters perceive it to be then.
