'Multiple Doses' of Poison

Rules Questions

Question: When multiple doses of the same poison are injected into a creature's system in succession (i.e. multiple stings from a centipede or wyvern), does the duration of the poison refresh?

I know the DC increases by +2 for each dose, but what happens to the 'frequency' of the poison? For example, if a wyvern stings a PC in round one, the PC is poisoned for six rounds. If the same wyvern then stings the PC again in round three, is the PC poisoned for six more rounds, or are the remaining four rounds of poison just more severe?

Whenever a creature takes another dose of poison from the same source, increase the DC by 2 and the number of rounds remaining by half of the total rounds.

The total rounds for the poison itself is 6, so additional doses would increase that by 3 rounds. If the PC only has 4 rounds left when he is stung a second time, then he would now have 7 rounds left.

When you are dosed with the same poison multiple times do you suffer the effects of the poison multiple times (IE the damage)?

No, you only take the damage once, when you save on your turn.

Example: A fighter is facing three Medium spiders (which inject Medium spider venom on a successful bite). Medium spider venom normally has a frequency of 4 rounds and a DC of 14. On the first round, all three spiders bite him and he fails all three saves. The second and third doses each increase the total duration by 2 rounds (half of the 4 round frequency) and the save DC by +2, for a total duration of 8 rounds (4 + 2 + 2) and DC 18 (14 + 2 + 2). Fortunately, Medium spider venom is cured after just one successful save, even though the fighter is battling three doses at once.

Example: This time, the fighter makes two of his initial saves against the spider venom, so he only has one dose active in his body. He fails his save on his turn. On the spiders’s turn, two of them bite him, and he fails both saves, which increases the duration to 8 rounds and the DC to 18, just as if he had failed all three saves in the same round.

Ok, but what if he is bitten by one of those three spiders next turn. Does he take the damage again?

Poison (Ex) Bite—injury; save Fort DC 14; frequency 1/round for 4 rounds; effect 1d2 Strength damage; cure 1 save.

The DC and duration go up, but the damage dose not.

The frequency is 1/round = he takes damage once a round till he saves against the DC.

1st round)
3 Spider Hit (DC14,1 fail, 2 save) duration 4 rounds
Fighter (DC14,1 fail) 1d2 Str Damage
2nd round)
2 Spiders Hit (DC14, 2 fail) duration 7 rounds (3 left, 2+2 new)
Fighter (DC 18, 1 fail) 1d2 Str Damage (Damage dose not go up)
3rd round)
1 Spider Hit (DC 14, 1 save) duration 6 rounds (duration dose not go up)
Fighter (DC18, 1 save) poison cured

Thanks :)
