Affinity

Level I	Mana cost -5 does nothing
Level II	Duration +5 does nothing
Level III	Amount +2 does nothing

A level marked does nothing changes nothing in this build: this spell has its own kind of affinity bonus, which replaces the shared bonus code instead of adding to it, so a damage or cost value stored on that level is never read.

Affinity is a spell's own mastery level and it carries between runs. Each level is applied on top of the ones below it. How affinity is earned.

Prestige options

Taking one of these cards from a boss chest changes how the spell behaves for the rest of that run. You pick one.

Derecho

Your Thunder Storm also causes intense winds and rain. While Derecho is active, water levels will begin to rise drowning both you and any monster within.

Fulmination

Your Thunder Storm begins with a crack of lightning that strikes at the center of your spell sigil for massive damage.

Maelstrom

While your Thunder Storm is active, a Maelstrom of hail showers down, inflicting frostbite on all monsters.

RiptideandThunder Storm

Lightning that strikes an enemy already in the wave makes Electrified Water.

Electrified Water: Stays on the ground and hits again on its own rhythm until it runs out; lasts 3 s; hits every 0.25 s; applies Shock. Takes its bonuses from Thunder Storm.

Shock: Each tick deals the Shock damage. No element bonus applies to it. 3 damage every 0.2 s for 0.5 s. One application: 6 damage (2 ticks). A second application refreshes the timer; it does not stack.
