Zenith

Description
Mark a 3x3 area centered on your current tile for a delayed explosion of 150 damage. Zenith has a cast delay of 0.15 seconds.

Strategy and Synergy
Zenith is a solid spell that is free to cast and can deal a respectable amount of damage, the only major downside to using it is the possibility of self-damage.

Using this right before dashing is the way Zenith is meant to be used, however there will be a few situations, such as boss fights, particularly those that invades your tiles often such as Shiso or Terrable, or reflecting the blast with Reva; in this case, at melee range, the base damage output will be 300. During those boss fights, you can predict where they will land, and cast it right before they appear, dodging upwards/sideway and avoiding the blast yourself.

Trivia

 * The flavor text "Use right before dashing!" effectively teaches the player how the spell is meant to be used when playing as Selicy.
