  • Now spellbook level command adds properly additional slots.
  • Fixed burnout cast cancellation, now it is correctly working with continuos spells.

Changes

  • Removed spell level debuff 
  • Changed the dominan spells config to make it more compact.
  • Changed command: spellCategories -> principle
  • Now shields can only block the first magic damage its received, and then a cooldown is applied to it. Just like an axe.

Features

  • Added spell power debuff.
    • Now exhaustion reduces the spell output of spells in a percentage according to the spell exhaustion level. This reduction is applied after the principle modifiers.
    • Now spell power debuff is applied to almost all types of spells.
  • Added the fatigue multiplier value config.
  • Added a passive for Potentia related to Projectile Accuracy
  • Added a passive for Expansio related to Radius (Currently visual entities aren't synchronized with this radius)
  • Added sound for spellbook level up.
  • Now spellbooks give you additional max exhaustion points, the amount of points is defined by the original spellbook slots.
  • Added Config for spell power multiplier for each exhaustion level.
  • Mana reinforcement barrier now have a small breath animation.
  • Mana reinforcement barrier now make you have the glow tag.
  • Now getting to the max exhaustion level and capacity will give you burnout.
  • Now casting while having a Staff in any hand will reduce 20% incoming fatigue.
  • Now the exhaustion produced by a spell is increased by the amount of principles as the complexity is bigger, each principle multiplies the fatigue by 5% at level 0, increasing principle level will reduce this multiplier, until max level when you get -5%.  
  • Added scorpio, cygnus, and sagitarius constellations to star alignment sprite pool.
  • Added mindful particles
  • Added Fundamental School (Spell power and magic resistance)
  • Added Certum Principle: This principle describes spells that can't be affected by exhaustion level directly in their power, maintaining its power or only being altered by spell levels, due to that, this kind of spells are the only ones that are affected by mana debuff. This cause the increment of mana consumption getting higher as exhaustion builds up. Leveling up this principle reduce this debuff.
  •  Added a config to define the mana addition for each exhaustion level exclusively for certum spells.
