Mobile Fortress

Engineer skill · Plating Line · tier 5 (ultimate)

Beta 0.7.2

The whole workshop becomes armour, and it walks.

It is only used in combat once it is placed on the hero's active bar, and its 16 s cooldown is before cooldown reduction.

Values by rank

Mobile Fortress scales with Health. Its value at each rank is 650 + 185 × rank:

Rank	1	2	3	4	5	6	7	8	9	10
Value	835	1,020	1,205	1,390	1,575	1,760	1,945	2,130	2,315	2,500
% of the hero's Health	8.35%	10.2%	12.05%	13.9%	15.75%	17.6%	19.45%	21.3%	23.15%	25%

The value is in basis points (100 = 1%) of the hero's own Health, before line mastery and synergies.

Health given = round(hero's Health × value × skill power ÷ 10,000)
skill power = 1 + 1% per point in the other Plating Line skills + 2% per rank of each skill that boosts it

Mastery and synergies

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

Mobile Fortress has no synergies: no skill boosts it and it boosts no other skill.
