Tribble Breeding for the Impatient... Please correct me where I am mistaken.
Looking through the various sources, it seems to me that the goal of breeding is to produce a (Tuf), which in turn can be bred up to either a (Mat) or a (Ric). These two are the basis for any of the rarer (non-unique) breeds, yes? (And, incidentally, what you apparently need in order to breed up a Cryo-Tribble using Snow Tubers.)
It also seems to me that a sub-goal is to use the cheapest, most available food possible. I want to buy it or replicate it, not wait for a food item drop.
To get a (Mat), I see the following logical progression (leaving out the lowest tier of tribbles):
Species: Sus/Vit [Heal] -> Tuf [Heal] -> Hen [+Regen] -> Dea [+Regen] -> Mat [+Dmg/+Regen]
Food: (Ferengi Snail Steak) -> (Chateau Picard) -> (Chateau Picard) -> (Saurian Brandy)
To get a (Ric), it looks like this is a logical progression:
Someone should add the cryo tribble to the breeding chart.
on the deferi missions, one of the rewards are snow tubers. open the crate and you have 10 of them. feed a snow tuber to a (ric) and you will breed a (cryo) tribble. i was lucky and got mine in the first feeding, but i have heard from other breeders that its not always so. So keep feeding (ric) and youll get a cryo tribble.
Also big point to notice. You can only breed one and only one cryo tribble. I tried with my remaining tubers and met with no success so if you make one enjoy it. Its also a bound item and you wont be able to trade it or give it away.
Hope this helps and thank you for the charts originally.
