New Spells:
Staves and Rods dropped by monsters now unlock unique Spellcasting mechanics, on top of increased damage/speed when compared to default spells. The new spell categories are:
 • Etherial Spells: These won't be destroyed upon collision, hitting multiple targets along its trajectory.
 • Explosive Spells: Explode upon hitting an obstacle, damaging enemies in the vicinity.
 • Web Spells: Create an AoE upon hitting an obstacle, damaging enemies that step on it.
 • Vortex Spells: Conjure an Elemental Vortex upon hitting an enemy. Vortexes will roam for a short time, dealing extra damage to anyone in their path.
 • Orb Spells: Conjure an Elemental Orb upon defeating an enemy. Orbs will pursuit the next closest enemy.

New Monsters:
Web-weaving critters have made their way into every arena. Defeat them for a chance to wield the highly coveted Critter Staff, unlocking the newly added Web Spell!
Furthermore, the Ruins Arena has been taken by Ninjas! They are the fastest enemies yet, but defeating them may grant the fastest spell that a Necromancer can cast, which also explode on contact!

Waves Rebalance:
Every arena has been carefully reviewed and the hordes of enemies have been re-written to ensure a more balanced and diverse gameplay.
