Which offensive spell causes the highest damage?

I made this and it works like a charm:

Section 1: fire (effect) + missile (carrier) + damage (modifier) + spray [w](modifier, the more the better) + ricochet (modifier, the more the better)

Section 2: air (effect) + enchant (carrier) + damage (modifier) + time (modifier)

As a result, you obtain the following: after firing the missile, it spray into W missiles (depending on how many cards you used), when it hits the target it deals X fire damage to the enemy who’s hit, in addition, after each hit it spawns a shower of anvils with Y area damage for a specific time. Bounced missiles hit another Z enemies (depending on how many cards you used), which also sustains X and Y damage

As i said the damage depends on the number of cards used, but this is the highest damage i can make so far
