Stormbind is a channellingspell that places runes on the targeted ground as the skill is channelled. These runes hinder enemies standing on it. The gem grants a sub-skill, Rune Blast, which improves runes placed by Stormbind as it is channelled, and releasing the channel detonates the rune and surrounding runes to deal lightning damage.

Stormbind
The Stormbind skill places runes in a grid pattern around the cursor. These can be improved with the Rune Blast skill to increase damage and area of effect. If using two Stormbind setups (one to place runes, one to improve runes), support gems that increase damage should be linked to the Stormbind setup used to place runes.
Area of effect - Runes will always have the same distance from each other regardless of your area of effect modifiers, but the Rune Blast explosion area of effect, which has a base of 16, does increase with modifiers and by upgrading runes, and can overlap.[1] Multiple runes can hit a single target.[2].
Rune Blast
A Rune Blast from one Stormbind gem can still improve the runes of a different Stormbind gem.
Rune Blast does not have the same gem tags as Stormbind. It is a generic channelling skill and does not directly deal damage.

Increasing the mana cost used per channel tick increases the number of connected runes improved per cast. Each rune can only be improved once per channel tick.[3] If the mana spent exceeds the threshold to improve, the remaining mana spent can also improve any of the 8 surrounding runes. Up to 9 runes can be improved per channel tick this way.[1]

A level 20 Stormbind that costs 48 mana per channel tick and ticks 10 times per second improves 2 tiles per tick. It would take at least 1.5 seconds to fully improve 9 runes.
