The Summoner Mage in "Dragon Age: Shadowkeep" is a very useful and powerful profession in the game, and the Summoner Mage has many useful early skills. The first is Frost Nova, which has the effect of freezing the surrounding area. Area and Enemy (area, control), position is the first control skill.
What skills are useful in the early stages of Summoner and Mage in Dragon Age 4
Summoner Mage has the best skills early on. By combining burst and control abilities, they get a lot of options that help them build the cold damage heavy abilities they need. Bastion and Fade Reflections from the Deathcaller selection also make sense, giving you more versatile options.
However, it's hard to ignore the skills Summoner has to offer. Most of the early abilities, like Frost Chill and Frost Shield, along with the early ability Frost Nova, all work together to build the idea of a cold mage. Then Fade Conductor will help you cast spells more often, and Perfect Cast is an easy way to increase your damage in combat.
