To craft a synergy shape you need to upgrade a legendary shape to a unique shape.
You'll then get this screen asking you what you'd like to create:

Choosing non-synergy will simply give your spell a random bonus but will not let you choose a synergy. It's still good but that's not why you're here.
Choosing synergy will give you a new screen where you can choose what synergy to build.

Keep in mind when choosing a synergy to play with, you need both the primary and paired sigil equiped for it to charge and cast.

A tornado that slowly moves toward enemies, pick them up and burns them to death. Strong control and damage.

A larger size aoe that does huge damage. Very fast and very strong burst. Excellent at dealing with stronger enemies in seconds.


A controling pool spell which prevents any movement, casting and teleporting, while damaging enemies. Amazing in narrow entrances which enemies need to pass.

Summons a storm cloud which slows over a massive radius while freezing enemies in a smaller radius. Lasts a long time, great at controling a whole area of enemies.




An aoe type spell which draws enemies in for a few seconds then explodes dealing heavy damage. Good spell if you need a little breathing room.

A big fireball throwing tower of a golem. Stays in one spot and attacks any enemies it can see and explodes at the end of it's duration. Does a good amount of damage and lasts a fair time. More of a strategic spell, it's great for supplementing your damage in prolonged battles.

To cast a synergy spell you first have to fill the synergy meter.
This is done by getting overkills.
Hitting them with one of the two synergy sigils then killing them with the other nets a bonus to the synergy meter

Once the meter is filled just cast an AoE spell from the primary sigil and enjoy the fireworks.

This is a very quick guide, I'll put more effort in later.
I'll add descriptions of the synergies in the future too.
Feel free to post things to add in the comments.

Thanks for reading and enjoy the destruction!
