[RPG] frenzy after enraging or do I have to frenzy when I begin the rage

dnd-5erage

For reference Frenzy says:

you can go into a frenzy when you rage

Best Answer

You can only choose to begin a Frenzy when you begin a Rage.

The effect "you can go into a frenzy" is contingent on the condition "when you rage", not "when you are raging" or "at any time during your rage".
