Shattering Barrage 
Spends all mana to encase the target in ice, stunning it and increasing damage taken by 100% for up to [mana / 150] seconds. All icicles are then fired at the target. Duration is reduced by 75% on Bosses, to a minimum of 2 seconds.

Level Bonus:
-1 mana divisor
Icicles 
Attacks have a 15% chance and Icy Bombardments have a 5% chance to create an icicle on hit, which is stored and waits to be fired. Stored icicles passively increase attack damage by 5% and mana regen by 0.5 mana per second each. Maximum of 5 icicles. At maximum icicles, any more icicles created are instantly fired at the target. Each icicle deals 3000 Frostburn damage on hit and permanently increases the damage dealt by future icicles by this tower by 2%.

Level Bonus:
+0.4% chance on attack
+0.1% chance on Icy Bombardment
+80 damage
+1 max icicle every 5 levels
Icy Bombardment 
Attacks have a 15% chance to fire a projectile at a random point within 150 range of the attacked creep that deals 25% of current attack damage as Frostburn damage in 200 AoE splash. Each additional projectile has a 30% chance to fire another, up to a maximum of 4 per attack.

Level Bonus:
+0.4% initial chance
+0.4% additional chance
+0.6% damage
Frostburn 
This tower's attacks and abilities deal Frostburn damage. 50% of the damage is dealt immediately as attack damage. 100% of the remaining damage is dealt as spell damage over 5 seconds. If this effect is reapplied, any remaining damage will be added to the new duration.

Level Bonus:
+1% damage over time
