The main point of Master of Eternity is to go through the campaigns per chapter and defeat all the evil mechs. It involves forming a team with a powerful suit. In this list, I checked all of the assault suits available and wrote down some information about them to help you decide who to raise later on.
It has a high defence and HP but the downside is, it has very low attack power. Therefore, this suit is best used as a tanker. It has a good skill that knockbacks the opponents making it perfect for setups during a clash. The thing is, this suit falls behind the other suits as the game progresses. It's a good suit, to begin with, but not later on as you get stronger.
This is one of the suits that you will have when you begin the game. It's perfect for a beginner. It has charge and stun as its skills together with its area burst. But the problem with this suit is, its HP and defence are low compared to the other suits. The thing with assault, it should be a tank but Grash fails on that aspect although its stun and mobility can help you during your early games but not when the level of difficulty is higher.
This is one of the less useful suits in the game. It has a mana burn skill but it's not useful because enemy mana starts at 0 in the game. It also has a freeze skill but the problem is, even the enemy is frozen, it can still attack. Overall, combining its low stats and skills that are not so useful, this suit can be skipped.
Darr is an average suit. It has a very useful dash skill that gives an extra defence, making it a good tank. Also, its advantage is it doesn't use a lot of mana, and it can even add extra skills, unlike the other suits. It might not be that special, but considering its skills and stats, it gets the job done for you.
This is a great suit, and make sure to raise it once you have it. It has a mass stun that can hold many opponents, therefore you can do free attacks. Although it has a short range and low damage, it doesn't matter because that's the job of your assault suits to do the damage.
