Maybe dont eat a bio and it wont kill your dragon (unless your an asd?)
You know the getting high effect (by eating shrooms after the effect goes away and repeat it 5 times might leave you on 25% hp or lower...(turned up to 11 if you eat a bio or bite into it, aka if your not an asd this will effect you)
Also make a bios spit also has the effect of the blooper of mario kart.. But lasts like 10 to 30 seconds max.. Just enough to go poof.... (Yes people will just start shooting bios instead but its better then no defense)
Thats defensive as well..
