Riven Spark

A bolt at the nearest foe splits in two behind it. It aims itself at the nearest elite in range, or the nearest monster when there is no elite. Every foe it hits takes 1 shock stack: each stack makes it take 10% more damage from every source. Stacks last 4 s from the latest hit, 3 at most.

Play

A level-up offers it as one of three cards.

Rank by rank

A level-up card offers a skill you do not have while one of your 6 slots is free, or the next rank of one you have, up to rank 5. These are the lines the card shows:

Riven Spark’s numbers at each rank
RankCooldown (s)DamageBranch (tiles)
14222.5
23.8272.75
33.6333
43.4403.25
53.2483.5

At every rank: Range 7 tiles.

Evolution: Sundered Spark

Rank 5 + Whetstone → Sundered Spark. Hold Riven Spark at rank 5 and any rank of Whetstone, and the next level-up’s first card is the evolution, drawn in gold. A heavier bolt with longer branches, and all it touches is shocked twice.

Whetstone is also the key to Rime Splinters, so one passive can open two evolutions.
