Judgement Call: New Creature Ability
I'm trying to put together Coda creature stats for the neural parasites from "Operation: Annhilate!" and I want to create a new special ability, Colony Intelligence, to simulate the enhanced collective Intellect of a large group of the parasites. What I have in mind is an ability that grants +1 to Intellect per 10 creatures in a colony, to a maximum Intellect of 13 or maybe 15 (depending on how nasty one wants to be). To make the ability more generally applicable, perhaps it should be possible to reduce the number of creatures required for the bonus.
I'm thinking of this as a fairly nasty ability, because more creatures are already harder to deal with, and if run properly the Intellect enhancement is going to make for very tough going for a group of player characters. I'm considering a cost of something like 10 or 12 advancement picks for the ability, +3 or +5 for each 2 fewer participant creatures required to gain the +1 Int bonus.
Does that cost seem reasonable, or perhaps even a bit too low--or am I overestimating the value of the ability?
An opinion from one of the Coda Crew would be invaluable to me, but I would like to hear what anybody has to say.
