Violette (Boss)

Description
Violette is the only boss that uses attacks bound to the rhythm of her theme music. While familiarity with the soundtrack is not required, players should be aware that certain sections of the song feature syncopation that will cause sequences of attacks to hit more rapidly.

When spared, Violette will occasionally appear at the start of battle and buff the player, giving them 40 shields, 3 spell power, and increasing their max mana by 1 for the duration of the battle. This buff is applied by launching a note that hits the tile the player is on; this can be "dodged" by quickly moving away, and the buff will disappear after a short period if the player doesn't walk back on the tile.

Strategy
Spells and Artifacts that grant are especially handy during Violette's note attack, since it allows the player to miss a few notes and still prevent any  damage. The player should also be very wary of during this attack, since shuffling removes a large chunk of the player's shield, which means that her attack will likely deal high amounts of damage to the player. For the same reason, taking the Sell Shield pacts from the Shop before the fight is a very bad idea, as they drain shield very rapidly. also drains shield, but it's much slower, meaning that the shield loss can easily be mitigated using spells.

The player should also make sure to have a way to quickly deal with her Speakers, as they will make the following attacks much more challenging if not destroyed in time.

Patterns

 * Her main attack, which she always opens with, consists of a series of green note symbols marking certain tiles on the player's side of the grid as she plays; If the player is on said tile as it "hits", the player character gains 30 shields. After several seconds of this, Violette hits the player with an undodgeable attack, the damage of which is based on how many notes were played, and her Tier: At tiers 1 and 2, she deals reduced damage, meaning the player can miss some notes and still not take health damage. At tier 3+, she deals the full damage, meaning the player can't miss a note if they don't want to take HP damage. Note that if you hit all the notes, being hit by this attack does not invalidate a flawless victory, even if you somehow lost the shield through other means (Like shuffling your deck), but it does if you miss a note, even if you still have enough shield to not take any HP damage. Fragile also does not affect damage taken from this attack.
 * Purple rays hit, from right to left, each column of the player's grid: The higher tier she is, the more tiles will be hit each column, with Tier 4 having every tile be hit, meaning the player can't simply position itself in a tile that won't be hit. In addition, from Tier 2 onward, she also attacks with a note aimed at the player's current position; it is not in sync with the regular beat, having its own tempo instead. The higher tier Violette is, the more frequent this note attack gets, and at tier 5+, she attacks an entire row with it at a time. Both the rays and the notes deal 80 damage.
 * Summons 2 Speakers with 100HP each, at least one tile apart from eachother, on the player's side of the grid. These attack with several different patterns of waves originating from their position, from merely hitting all surrounding tiles to hitting the 2 closest tiles in each cardinal direction; these attacks follow the beat of the song, but at half speed. Note that these can be damaged and destroyed by Violette's purple rays.
