Superior sigil of Luck
I speculated a bit on some of the magic find gear, and this was one of the pieces I picked and stock-piled. Unfortunately.
In PvE – There are a dozen better sigils, and as Engineers, we can trait VERY heavily for boons anyway, so this is lacking in about every department.
PvP/WvW – S/d thieves, Necro’s Corrupt Boon, and the ‘on kill’ requirement make this as much a liability as a benefit.
This is only my opinion, but judging by the price, I would guess I am not alone.
Physti – Elementalist | Fistful of Blades – Thief
[WHIP] Quaggan Slavers – HoD
It is very common in WvWvW for all classes to stack up bloodlust/corruption/perception and then swap that weapon out for other sigil. Due to stacking problems on proc sigils people (atleast big part of the top guilds who know that they constantly get kills) often use Stamina (endurance refilled with kill) on atleast one of their weapons.
However I would say if that class already has perma vigor, or using Energy sigil, or some other method of regularly filling that dodge bar. It’s probably better to use Sigil of luck over Stamina. So for 2 weapon engineer with vigor kits I say it’s definetly worth trying after kills stacks, over Stamina.
The only time I think it can be considered useful is when fighting a thief or mes in wvw and they stealth and dump all the aggroed animals on to you. Might as well turn all that dump into boons
