prevent damage and poison counters

[MeddlingMageGR]

Is there any ruling about prevention of the damage, from creatures with poison counters?
For example Forcefield. If a poison creature attacks me for 3... and I pay 1 mana for Forcefield, will I get 1 poison counters? Or 3 ?

If you're talking about Infect and not Crypt Cobra, it's pretty simple - infect is just plain old damage. Take one damage, get one poison counter.

To slightly add to what cdr said:

Damage ordinarily results in life loss. With an infect creature it results in poison counters. So if something prevents damage then it would prevent both resulting lifeloss or poison counters. In this case Forcefield has actually had an errata causing it to prevent damage meaning you're set either way (except that one damage that slips through) but I am guessing that if forcefield still prevented lifeloss it would do nothing.

yes im talking about "infect". A 1/1 creature with infect, if it gets pumped you receive more poison counters. As many as its power. In your example with Crypt Cobra the power of the creature has no connection with the poison counter. You get 1 even if you pump the Cobra.
So, does the Forcefield prevents the poison counters (all of them except 1) the same as prevent damage ?

Again, infect *is* damage - you get as many poison counters as damage is dealt to you.
