Notes

• At all ranks, it will take 40  Toxin procs to reach the maximum bonus.
• Stacking Primary Blight requires the Toxin proc to come from the primary. Warframe abilities that add Toxin to your weapons, such as Saryn's Toxic Lash, also work.
• Similar to other Primary Frostbite, Primary Blight stacks expire all at once after 12 seconds of no procs, rather than only 1 stack every 12 seconds.
