whats a time elixir (P)?

I just got a time elixir (P) from the event. How does this differ to the normal time elixirs?
Is this one worth more or expires after the event or something?

Thanks a lot.

The (P) potions and time elixirs cannot be traded, since it denotes 'personal'.
When you're using potions or time elixirs, the personal ones will always be used before the tradeable ones.

time elixir (p) is non-tradeable, so is of no use in try to trade for better cards. many 4* cards and pretty much all 5* and 6* cards are traded for time elixirs (TE) only.

they do not expire and are probably best saved for events where you can earn BT points by spamming quests and/or battles.

thanks for the reply guys
