Mammoth Matriarch

Overview
The Mammoth Matriarch made its first appearance during the Animal Invasion event. It was encountered in a Level 22 encounter named after itself, "Mammoth Matriarch", where it is accompanied by 8 other mammoths, a mix of Tusklings and regular Mammoths. It was permanently made an infrequent member of Critter invasions after the Raiders vs. Bottle Rockets event, and later became a highly common opponent in Wild Bunch invasions and wild Mammoths on the world map.

The Mammoth Matriarch is the mother of all mammoths, as the name suggests. It boasts the highest HP and damage of any Mammoth you'll face. Fortunately, it lacks any real defense, so concentrated fire in the first few rounds will remove this threat.

The Mammoth Matriarch's attacks have a global cooldown, so it can't attack on two consecutive rounds. You'll always have a breather after a Matriarch attacks.

The Matriarch's second attack, called Shake the Earth, has a 1-2 range and will attack the entire row. Despite being Contact, if the Matriarch can target an exposed unit on the 2nd row, the attack will hit EVERYONE, even if units are hiding behind other units on the first row.

It is worth noting that groups of mammoths, which include Mammoth Matriarchs, will start to spawn fairly frequently at later player levels, and will serve to be nice tools to aid  and  farming. A good way to take advantage of this is to use units with fire attacks, such as Salamanders or Light Chemical Tanks.
