Detailed Skill Descriptions for Poison Bow Skills are Broken

None of the poison bow skills (Poisonburst, Toxic growth, vine arrow and gas arrow) are displaying their poison stats, among other things. All three skills appear to scale off of projectile damage (even the gas cloud in Gas Arrow), which makes no sense considering the projectile isn't the portion of the skill dealing the poison damage.

Toxic growth is guaranteed to poison, despite it not being mentioned.

Envenom (chance to poison support) is also saying it's giving me 72% chance to poison, instead of the listed 60 (I don't have any on the tree).

Do these skills scale with projectile damage? I understand the arrows themselves should, but if the clouds/burst do as well, I'd love for that to be included in the skill description.

Toxic growth and vine arrow says they can be poisoned to deal more damage, but they can't actually be hit by attacks, necessitating gas cloud or the splash from poisonburst. There's also no mention of how many poisons can be applied. This one might be intended, but I feel like it's extremely clunky. I understand this could be to prevent fork shenanigans, but forcing all projectiles to pierce would also solve that issue without making the skill feel worse to use. I'm fairly sure this mechanic uses the total poison damage, not poison DPS, but it isn't specified so I just want to make sure that's correct
