Scourging Slayer

The lightning bound into this blade is erratic, ever searching for something to strike.
Overview
Scourging Slayer is an enchanted version of the ordinary sword. It deals slash damage and adds 10 lightning damage, with a 25% chance to trigger a chain lightning effect that strikes nearby enemies and deals the same damage. Enchanting it resets any upgrades on the normal sword, so it is effectively built from a fresh base weapon rather than an already improved one.
Its attack pattern is sword-like but has some notable reach characteristics. The primary combo swings are fairly vertical and cover a wide area, while the third strike in the combo is narrower horizontally. Its secondary attack is a long-reaching thrust that can outrange most enemies and deals very strong damage.
Scourging Slayer can be upgraded to increase its slash damage and durability, while its lightning damage remains constant at 10 across all quality levels. The upgrade path is:
- Quality 1: 170 slash, 10 lightning, 200 durability
- Quality 2: 176 slash, 10 lightning, 250 durability
- Quality 3: 182 slash, 10 lightning, 300 durability
- Quality 4: 188 slash, 10 lightning, 350 durability
Crafting costs for each quality are:
- Quality 1: 1
Slayer, 15
Flametal, 1
Iolite
- Quality 2: 15 Flametal, 1 Iolite
- Quality 3: 30 Flametal, 2 Iolite
- Quality 4: 45 Flametal, 3 Iolite
The total cost for a fully upgraded Scourging Slayer is 1 Slayer, 105 Flametal, and 6 Iolites. As of patch 218.15, only quality 2 is currently obtainable, costing 30 Flametal and 2 Iolites beyond the base weapon.
