Me and my friends (as non-native english speakers) are having trouble getting the timing of Potion of Heroism. I copy the relevant text for reference:
For 1 hour after drinking it, you gain 10 Temporary Hit Points that last for 1 hour. For the same Duration, you are under the effect of the bless spell (no Concentration required).
The problem is in the first sentence. We don't understand why "1 hour" is mentioned two times, first related to the effect (gaining THP) and then related to the duration of the THP themselves . Currently we have two interpretations:
For one hour after drinking this potion (as an action), you can choose to gain 10 THP. These THP will last for an hour.
When you drink this potion, you gain 10 THP that last for an hour.
If it's case 1, it's unclear if the duration of the blessing spell starts when the potion is drunk or when the effect is "activated".
If it's case 2, the blessing spell lasts for one hour right after drinking the potion.
I have searched quite a bit, and haven't been able to find any clarification on this, nor anyone complaining about the wording. As a secondary question, is this wording clear and I just can't absorb the meaning properly, or is it a bit ambiguous?
