What is "Box Spell"?

[Kandidaten]

I have completed the game and I have no idea what this is still?

[TheraNord]

Only Amadeus can use that spell. When you cast the spell, he conjures a large box above his head, similar to Death Circle or Zap spell. To use it, press the throw button and when it flies above an enemy, press it again to slam it on top of them. It has good damage, and weaker enemies might be slain in one hit.

P.S If you have the Staff of the Artifact, boxes on the ground can be picked up and thrown again.

Yes, like TheraNord mentioned, it is a spell that Amadeus can use. And it is actually one of the starting spells for that specific character.

With Staff of the Artifact (found in the final level) you can pick the boxes located in stage 29 up - the picked up boxes will work very much like the spell (though there will be no bonuses from being Amadeus, no mana/cooldown, box aura/explosion) - you can try out the "generic" box that way, just bear in mind that the Amadeus' one is stronger in most regards (with the exception of 60s cooldown and low charges).
