EAT ALL THE SUNDIALS
Would eating Arsenic and Thorn Carapace induce poison? Would Procrastination induce Stasis? Would Permafrost induce Freeze|Congeal?
Good question!
I would say:
Poison on Arsenic, 75% chance of poison on Thorn Carapace, 1 turn of delay on Procrastination, same chance when blocking to Freeze on Permafrost (i forgot the exact chance!).
Simple is probably best.
Sure, i was trying to say that the shields should behave like when blocking (so a Fire Shield should deal 1 damage, a Skull shield has a probability depending on HP to turn it into a skeleton and so on).
But maybe it's best to avoid complex interactions, since it's difficult to eat permanents anyway!
Sidenote: when saying "non-pillar permanents" it also means "non-pendulum" and "non-tower". It should be obvious, but it's better to point it out.
