Ahhh, forgot that. Anyway, on to the flavor. Do you have any ideas?
Hopefully not mixed with wingless wonder. Yuck!
Well, I've read through the original descriptions of both versions, and I'm not coming up with a whole lot. Maybe this:
Alkada are bizarre creatures, apparently frail but with surprising psionic abilities. They exhibit almost childlike personalities as they wander the world, but .... ???
This conversion will never end!
Both of them (the Menzo version in the text, the Magister version in the statblock) say they are immune to fire, so let's give that to both versions.
I would also support giving the same poison flesh to both. How about something like 1d4 Con plus X rounds nausea primary and 1d4 Con and X minutes sickened secondary damage?
How about this?
Poison (Ex): Eating alkada flesh exposes the eater to the following poison:
Alkada flesh: ingested, Fortitude DC X, initial damage 1d4 Con plus 2d10 rounds nauseated, secondary damage 1d4 Con plus 1d6 minutes sickened. The save DC is Constitution-based.
Feel free to play with the numbers.
