Converting 3.5 Poison

[Kaoshin]

I can't imagine this thread hasn't come up somewhere in the past on this forum, but I ran a couple of searches and could not find it amidst the mass number of discussions concerning poisons so I figured I'd ask and hope for the best.

I'm currently running the Savage Tide module and am converting the monsters and characters to pathfinder as I go (given the module was written for D&D 3.5). I'm not very knowledgeable in how to convert 3.5 poison rules to pathfinder though when it comes to the poisons that have not already been converted for me. One monster has an injury poison that is DC 18 for 1d6 Con damage, and 2d6 Con damage a minute later. Can anyone recommend a good conversion to pathfinder for this poison?

You might ask in the Savage Tide subforum and see if anyone's done a conversion of that particular monster.

When I've had to convert a poison without a Pathfinder equivalent, I've looked on the poison table for one with the same DC and used that as a guideline for frequency and effect.

That's somewhat similar to a Wyvern's poison (in 3.5, it had 2d6 Con damage both initially and secondarily). The PF version has 1d4 Con damage 1/round for 6 rounds, with cure as 2 consecutive saves. I think I'd go with that (or 1d3 Con damage, as that would be closer to the total possible amount of poison damage from the 3.5 version).

The save DC is calculated based on the creature's number of HD and CON modifier (10 + 1/2 HD + CON), so that should follow from the creature's other converted statistics.
