Here's a digging bolt wand I used to kill a powered-up Toveri.
Spell by spell breakdown:
Double Spell draws 2 spells to the outer cast state.
reduce spread makes the outer cast state more accurate and draws 1.
The Spark Bolt Trigger creates a new inner cast state and draws 1.
Each Add-Mana spell adds 30 mana to the wand and draws 1.
The Divide by 2 spell draws 1 and makes the following spell happen two additional times.
The Divide by 3 spell draws 1 and casts the following spell happen three additional times.
Critical on Water adds 100% crit chance and draws 1. Both of these effects happen 6 times from the divide by spells, and an additional time due to the spell itself for a total of 700% crit chance and 7 draw (as if it were a multicast spell).
Seven Digging Bolts, each having a base of 8 drill-type damage.
Material Water since it belongs to the same cast state as the Critical On Water spells it grants 700% crit to all other projectiles in the cast state. Which has the effect of multiplying their damage by 35. This is also the last spell in the inner cast state.
Finally we have a chainsaw, which sets the cast-delay to 0 so that the wand can cast again on the very next gametick. This chainsaw was drawn by the Double Spell at the very start of the wand.
Lastly, a Light spell draws 1, which since there are no more spells after it, causes the wand to wrap, casting the whole thing a 2nd time before reloading.
So, the damage from the wand is 8 drill damage times 7 spells per cast times 35 for the crit multiplier times 60 frames per second times 0.5 because Toveri has a 50% resistance to drill damage. For a grand total of 58,800 dps. Atleast by my calculations, it's possible I made a mistake somewhere. Tovari died a lot faster than I expected. Also, the wand doesn't work right if the Triple Spell is moved any later in the wand. The divide-by spells work in mysterious ways.
