Feat
One Predator
Two bodies strike with the same instinct
The bond between the Ranger and companion has grown deep enough for either to exploit an opening perceived by the other.
When the Ranger rolls a natural 20 on the accompanying d20 of an attack, the companion's next successful attack before the end of the following tick becomes an automatic critical hit. When the companion rolls a natural 20, the Ranger gains the same benefit.
The transmitted critical uses the receiving attack's normal multiplier. It does not itself count as a natural 20 and therefore cannot transmit another critical in return. If the beneficiary lands no attack before the end of the following tick, the opening is lost.
