The question is simple but I can't find an answer anywhere:
If a creature hits one PC twice with the same attack that inflicts ongoing damage (save ends), does the ongoing damage stack?
1a) If so, does it require a save for each stack?
If two identical creatures hit one PC with the same attack that inflicts ongoing damage (save ends), does the ongoing damage stack?
2a) If so, does it require a save for each stack?
