Rainmaker shield

The Rainmaker shield or Rainmaker barrier is a protective bubble surrounding the Rainmaker. Players must attack the shield in order to pop it and reach the Rainmaker weapon. As the player attacks it, the Rainmaker Shield grows in size and changes to the player's ink color. Attacking a shield enlarged by enemy ink will shrink it back towards it neutral state; thus, if opposing players are dealing equal damage to the shield, no progress will be made. After enough damage is dealt to the shield by one team, it explodes and releases a blast of ink that is lethal to any member of the opposing team who is standing too close.

If a player carrying the Rainmaker falls out-of-bounds or into water, or if the Rainmaker is left untouched for too long after the shield is broken, the Rainmaker shield will always respawn in its original state in the center of the map.
