Taking 0.5 Damage Sometimes

Sometimes when fighting monsters, I take 0.5 damage and I have high DEX. Is it because “dodging weaker attacks” was implemented or is it a bug? It seems to happen sort of randomly.

I think the 0.5 damage is the dodge, but I could be wrong.

Dodge happens when there is no damage at all, so no damage will be shown and 0.5 damage is just a high enough defense I believe.

I’m pretty sure it’s not high defense considering I take normal damage part of the time.
