When my 20th level PC ingest a 5th level poison, how do I handle RR?
20 vs 5?
Or something else?
In RMC I think that 'Con Stat Bonus / 5 => PC lvl' is ok.
For example, with a CON Stat Bonus of 15 my PC is like a 3rd level against poison.
What do you think?
This is how I handle poisons.
IF a poison enters the system, then the minimal effect of the poison will be suffered, be it by blade, bite or ingestion. The rr is made to determine if moderate, severe or extreme effects are suffered.
A poison is a biochemical FACT. All poisons will cause a certain amount of harm. Some are devestating. If a player declared he slit his own throat, and assuming the PC makes any Sd roll you might demand, would you roll the crit, or just declare the damage (such as 10 hits a round, heart stops in 12 rounds)?
How any poison is delivered to the system will determine the rr mod assigned;
A crush +20
B crush +10
C crush +0
D crush -10
E crush -20
A slash -20
B slash -40
C slash -60
D slash -80
E slash -100
A puncture -30
B puncture -60
C puncture -90
D puncture -120
E puncture -150
If a poison is simply eaten, I'd go straight to EXTREME effects. Constitution wil not protect you from venoms or any other chemical soup.
