I may be wrong, but from experience,
1.]
While
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
purified, and one charge left, if hit with
![Time :time](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/time18x18.png)
neurotoxin, you lose a point of purify your charges, and still receive neurotoxin card-play-induced poison.
i.e.
1. i have +1 charge of
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
purify
2. opponent hits me with
![Time :time](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/time18x18.png)
neurotoxin
3. i lose my last
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
purify charge
4. every card i play will make me receive a
![Time :time](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/time18x18.png)
neurotoxin charge even though it doesn't display
(probably a visual bug; highly unlikely intended but possible)

Catapulting a
