One of the players in my game plays a rogue and asked me if the bleed from the Bleeding Attack rogue talent would multiply on a crit. We're both aware that the sneak attack dmg itself would be unaffected, but my player argues that the bleed is triggered by the sneak attack, as opposed to being part of the SA itself.
I've tried looking over the rules, but as far as I can see, there's no clear statement over whether bleed damage gets multiplied on a crit in general. While the wounding enchantment and some other bleed effects specifically say they don't multiply on a crit, I can't find anything on whether other bleed effects would.
So I put it to this forum, are there instances where bleed dmg multiplies on a crit, and if so, would bleeding attack be one of those instances?

Question's in the title, I know gaseous form allows the caster to fit through narrow openings, but could one fit in a jar or similar container held out for it?

So, I've just started a new campaign after a real long runner, pretty fun, but some of the players started to get tired of playing the same character for months on end. Relating to this, one of my players approached me recently with an idea where each player has more than one character. Basically, each player would have a roster of two-three characters they can choose between for adventures, with wealth and loot being shared out between a player's characters (I.E. This wand is useless to my monk, but my wizard could use this!). The idea would be to keep things fresh for some of the players while also allowing more experimentation with party composition.
The player himself has offered to do any book keeping for some of the less organised players and nothing about this strikes me as particularly outrageous, aside from having to take wealth distribution and experience per adventure into consideration, but has anyone done anything like this before?
If so, any advice on what to else watch out or account for aside from that?
