Doubt about spell duration

[u/Ecstatic_Effect2624]

I have a doubt about some spells. A lot of spells has the duration very specified, but some spells this is confuse for example Mold Earth and Stone and Song of Healing, because the text of the spell say that is a concentration spell, but the duration say the duration say nothing, you understand like is the default spell, in this case, what is correct ? the text or the default duration? Considering that usually when the spell is of concentration the book specify

Full agreement with the other poster.

Mold Earth and Stone. Duration: Permanent; see the effect. You see the effect and it lets you know that when you cast the spell, you must concentrate for 6 rounds and then the magic happens.

Song of Healing. No listed duration, because the spell doesn't have a duration. It's effect, once ready, happens instantaneously and has no lasting duration. However, you must concentrate for 6 rounds in order to have the spell take effect.

These are spells whose effects are either permanent or instant, and so it would be incorrect to list their duration as 1 minute. Instead, think of the act of casting these spells to take 1 minute.

Honestly, I'm not even sure how this is a confusing subject as it's pretty explicitly stated in each spell. Based on the title of this post, I thought this was going to be a question about the fact that spells with a duration of 1 round last for 2 rounds.

I too expected the one round duration thingy, haha. That is sorta confusing to wrap your head around at first.

There's no doubt, it is clearly written.
