Frost Nova

Mage skill · Ice line · tier 2

Beta 0.7.2

Ice traps the horde and one block slides, hitting the others like billiards.

It is only used in combat once it is placed on the hero's active bar, and its 12 s cooldown is before cooldown reduction.

Values by rank

Frost Nova scales with Chill. Its value at each rank is 140 + 40 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	180	220	260	300	340	380	420	460	500	540
Chill	+1.8%	+2.2%	+2.6%	+3%	+3.4%	+3.8%	+4.2%	+4.6%	+5%	+5.4%

Chill is a percentage stat, so the value is used as written (in basis points, shown here as a percentage), times the skill power.

Chill = value × skill power
skill power = 1 + 1% per point in the other Ice skills + 2% per rank of each skill that boosts it

Line mastery: every point in the other Ice skills makes Frost Nova 1% stronger, up to +40% with all of them at rank 10. Its own points do the same for the rest of the line.

Frost Nova has no synergies: no skill boosts it and it boosts no other skill.
