Fix Wretched Defiler missing skill types

[leotianlizhan]

Wretched Defilers do not work with many skill gems due to missing skill types

Fixes # .

Description of the problem being solved:

Wretched Defiler's skill doesn't work with gems like Controlled Destruction and Spell Echo for some reason, even though Spell Echo clearly works in game. I looked at the spectre.lua file and compared the skill to another spectre's skill that do work with those support gems (Forged Frostbearer), and found it's missing [SkillType.Damage] = true, [SkillType.Multicastable] = true, . Added those to skillTypes and it worked (see screenshots below)

I'm not familiar with how the export works, I assume #addSkillTypes Damage Multicastable is all I need to fix this during the next export script run? I didn't run it either. Please advise.

Steps taken to verify a working solution:

• Add [SkillType.Damage] = true, [SkillType.Multicastable] = true, to skillTypes in Data/skills/spectre.lua
• Verify in PoB that hovering the support skill checkbox shows DPS increase
• Don't know how export files work, please advise if it's correct
