Momentum
Supports any damaging skill that you use yourself, causing it to deal more damage if you move a sufficient distance while using the skill. Teleportation does not count towards the distance travelled.
Very solid choice with strong damage or utility for most builds.
Gem Effects
After moving at least 2 metres during a single use of a Supported Skill, the rest of that use deals 40% more Damage

Practical tips you won't find on the tooltip
More Multiplier
This support provides a 'More' multiplier — multiplicative with other damage sources. One of the highest priority supports for DPS.
Gem Level Priority
Support gem level often provides bigger DPS gains than you'd expect. +1 gem level gear is excellent value.
How to Get Momentum
Use an Uncut Support Gem to obtain Momentum. These drop from enemies or can be purchased from the gem vendor once unlocked through the campaign.
