In D&D 5e, there are a number of poisons listed in the Dungeon Master’s Guide page 258. Most of these poisons deal poison damage or inflict conditions. I know that in Pathfinder there are many poisons which reduce ability scores, but I notice an absence of such poisons in this DMG list for D&D 5e. As a DM I’m considering introducing a wider variety of poisons, which also means considering a wider variety of effects.
Are there any examples of poisons in other D&D 5e materials which reduce ability scores?
