Spell modifiers that adjust the damage of the affected projectiles.
A Spell modifier that adds a very large amount of damage to a projectile while greatly slowing it down. Also adds some extra recoil.
The Speed Up modifier can help mitigate the speed reduction caused by Heavy Shot.
This spell can be used to great effect with a non-shuffle wand and a trigger (such as Spark Bolt) by placing the heavy shot after the trigger and before other spells. This will produce a combo that delivers the heavy shot affected spell like a payload, bypassing its slow speed.
It also has great synergy with Death Cross, because Death Cross does not self-destruct or get bounced away upon impact with another enemy. This allows the cross to deal damage continuously to anything touching it until it explodes.
Combining Heavy Shot with a cloud of mist type spell results in a deadly damage over time effect. Couple it with Homing for a truly devastating cloud that seeks out enemies and melts them in less than a second.
Synergises well with Chain Bolt as its projectile is barely or not at all affected by the speed decrease. Piling multiple Heavy Shot modifiers on a Chain Shot can create a very powerful auto-aiming wand.
