[General]

You can safely attack and withdraw underwater.

Prerequisite

Dodge, DEX 13, Swim speed

Benefit

After making a single melee attack, you can use the withdraw action (moving up to twice your swim speed) as a move action. You can only use this feat while swimming.

Withdrawing from combat is a full-round action (see page 143 of the Player's Handbook).
