In 5e most magic items are potions of healing or +1 swords and similar.
In fact this is untrue, and easily verifiable as such.
Im not a 5e expert...so i will clarify that healing potions, +1 swords, +1 shields, and similar seem to be the most common items that i have seen. And we have up to level 5 in EA. I will end the EA with like 40 healing potions. That means you are likely to find in a traders inventory more of these items then unique items.
I don't judge other players experience, I like unique and homebrew items. i have modded in 50+ of my own items for players to enjoy until the final game is released.
Is it Augsut yet?
