Torug's Pact is a craftable set available in all armor types. The 5-piece set bonus decreases weapon enchantment cooldown and increases potency by 30%.
This is often used in combination with an Infused trait weapon. This is especially popular on Tanks in certain Trials. With Torug you can get a 100% uptime of an enchantment like Crusher or Weakening, because you can reapply the Enchantment before it runs out. When we compare Torug's to Roar of Alkosh, Torug's is way more reliable, as you do not require a Synergy to activate it. You can find a good comparison of Torug's and Alkosh in this article. You can find a screenshot of an Infused Torug's Pact weapon with Crusher and Weakening Enchant with this link.
In addition, a lot of people underestimate the Weakening enchantment. With an Infused weapon and Torug's Pact it gets a value of 587 which reduces the damage of small monsters by around 25%-30% and the damage of bosses by around 15%-20%.
Non-Infused and Non-Torug's = 10s cooldown, 5s duration
Infused and Non Torug's = 5s cooldown, 5s duration
Infused and Torug's = 3,5s cooldown, 5s duration
Like mentioned earlier, this way you can reapply the enchantment before it runs out, guaranteeing an uptime of 100%.
