Thruster

Engineer skill · Overload Line · tier 1

Beta 0.7.2

Pushes the engine past what the manual recommends.

It is only used in combat once it is placed on the hero's active bar, and its 14 s cooldown is before cooldown reduction.

Values by rank

Thruster scales with Haste. Its value at each rank is 390 + 110 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	500	610	720	830	940	1,050	1,160	1,270	1,380	1,490
Haste	+5%	+6.1%	+7.2%	+8.3%	+9.4%	+10.5%	+11.6%	+12.7%	+13.8%	+14.9%

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

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

Mastery and synergies

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

Thruster has no synergies: no skill boosts it and it boosts no other skill.
