Brain dump of an idea…
CONDITIONS
Things like: Burning, Frozen, Bleading… Other?
You would take 1d4 damage at the start of your turn.
After damage, for free, you roll the D4 again to try and remove the condition. Removed by rolling a 4.
You can have a skill/ability/trait/tag etc of FIRE RESISTANCE (+1 a D4 save roll)
You could also remove some conditions by spending a turn to; put yourself out, improvise a bandage…
Frozen you would not be able to personally remove but someone could help you or cast a minor fire spell on you.
Let me know what you think! Just came to me whilst playing around with some other bits. Easy to remember, roll 1d4 for damage, roll 1d4 to remove the condition. You might have a + in your skill / trait list.
