Experiencing the symptoms of whatever poison you ingested or absorbed into your blood.
[Technically speaking, Byleth's been poisoned a hundred times over, but his Crest Stone was an industrious sort, functioning not only as his heart, but as his liver and kidneys too (but on steroids). As such, almost all poisons were broken down and neutralised, and thus he never really experienced any symptoms.
...strangely, hallucinogenic mushrooms still affected him, but did that count as 'being poisoned' when you willingly ate those and was mostly fine? (He mistook them as edible mushrooms, okay, but he supposed the experience had been mildly interesting)]
