Crit damage->crit effect [suggested change]

[Null_Error]

Crits are basically meaningless on elemental weapons right now. And, while it's reasonable for a damage type with some very powerful upgrades (scared sausage, snake, eyes surgery) to have one less stat to benefit from, that's kind of uninteresting.

To remedy this, I suggest making crit damage a bit different from just a damage stat (since right now they're basically "%damage, but inconsistent and requiring investing in/not dumping two stats instead of one") by having every weapon have its own unique crit effect, affecting things that are fun to tweak but which are too weapon-specific to work as items. A few example ideas (where x represents the stat currently called crit damage):
1: The lightning shiv could, on crit, have its projectile jump to an extra target at x% damage (or perhaps, for the sake of more synergies/better interaction with the higher-level versions of the weapon, release an extra projectile with x% damage).
2: Shotgun projectiles could pierce an extra target (at x% of the damage they would otherwise do).
3: Cactus club initial impacts could release an extra projectile benefited by x% of ranged damage, perhaps at a delay from the initial projectile-firing (cactus clubs already easily one-shot most enemies and usually have more of an issue with dealing damage to enough different enemies).
4: Taser crits could slow for an additional x% or in an x% wider radius.
5: Torch and wand crits could make x% of any burn damage left over on death transfer to the nearest enemy.

Perhaps crit effects could even improve with upgraded versions of weapons in some cases (e.g. the cactus club idea above getting more bonus projectiles on crit at higher levels).

I'm aware that some of the above ideas definitely suffer from player-suggested-idea-OP-ness, and crits currently seem to be an on-hit thing rather than an on-firing-weapon thing as some of these ideas would require, but crit damage and crit chance are already stats I find myself going for on approximately 0% of my runs, and if this is a shared experience, making them more enticing seems like it'd be worth it.

getting an extra bounce or an extra projectile on crit could be cool. I think it could just do 100% damage, and I'd include the Taser in this too. Not sure about including the Shotgun.

I don't really like your fire idea, but I have no ideas that are any more interesting than "more/faster fire damage"
