Dear players, welcome to , The Warhammer information from the official forum, we just give it a Summary. We sincerely hope it can help you more or less.

You can do burst damage on a Magus, and no it isn't "bad". The problem is that its easily healed through, but if you coordinate with others (a squig herder using ranged heal debuff is best), you can be effective. There are 2 main ways to do this, either spec Havoc or Changing. Here is a very breif explanation.

 
In general:You need nearly capped INT (around 1000), as much magic power as you can get (hopefully at least 200), and as much crit chance as you can get. Defensive stats (wounds/tough/armor) aren't important for being able to burst (but they are for staying alive to do that burst obviously, but its more important you have the burst first).

 
Havoc:You NEED and erosion proc (this is a damage debuff). You can get this with jewlery that are tome unlocks (look up worldbreaker band on wardb), and when you get higher RR, you can get the proc with Invader gear and drop the jewlery.The key is to use the right tactics, and learn the travel times of your abilities. For example, Surging Violet has almost no travel time, as soon as you hit the ability, the target takes damage. Bolt of Change or Mutating Blue Fire for example, does, so use this to your advantage.

 
Then line up abilities at the right time, and use the right tactics, the +15% damage on Withered Soul is a MUST, and you must get that on your target before you burst them. The 50% more crit damage tactic on Surging Violet is also great for burst (as well as the -7 second cooldown, or the 15% crit chance for havoc spells).
