 Description? Debilitate deals no damage but gains up to 6% per rank extra duration from shield value. (Update) Armour 3

Bulwark is an Invention perk that lengthens the duration of Debilitate but decreases all damage it deals to 0. It can be created in armour gizmos.

Bulwark's extra duration seems to be a minimum of +1 game tick per rank. The only shield tier where the increase in duration is larger than +1 per rank is tier 90 (and only for rank 3). This does then mean that using debilitate without a shield will still see an increase in duration from the Bulwark perk for all ranks.

Bulwark increases Debilitate's uptime by 2.4 seconds out of 30 if used with a tier 90 shield. This is a 17.3% increase, resulting in 8.65% overall increased damage reduction provided the player uses the ability every 30 seconds when it comes off cooldown, has 100% hit chance, is fighting against one opponent, and damage taken is not classified as hard typeless.

## Calculations

• The length of time (in game ticks) that Debilitate lasts with the Bulwark perk, $t_{B}$, is
$t_{B} = t + \max\left(R,\left\lfloor t \times .06 \times R \right\rfloor\right)$
Notes
• $R$ is the rank of the Bulwark perk.
• $t$ is the length of time, measured in game ticks, that Debilitate would last if the Bulwark perk were not used. This value does include the tier of shield being used.
