Duration Support - Tuning Stone | Diablo 4 Season 3

Duration Support is a Tuning Stone with the following effects:
Supported Skills have their durations increased

I have yet to input rarity or tags for each stone!

Like all tuning stones, Duration Support can modify Governing Stones it's "compatible" with (see it's tags).

Up to six Tuning Stones can be used on a Seneschal Construct (3 for each Governing Stone).

Duration Support can be leveled up by obtaining DUPLICATE copies of itself.

Duration Support and all other Tuning Stones were released in Season 3.
