The Warlock talent Decimation would be a good candidate to study for a new Spell Alert.

Talents:

• rank 1 https://www.wowhead.com/wotlk/spell=63156/decimation
• rank 2 https://www.wowhead.com/wotlk/spell=63158/decimation

Buff:

• rank 1 https://www.wowhead.com/wotlk/spell=63165/decimation
• rank 2 https://www.wowhead.com/wotlk/spell=63167/decimation

The texture could be displayed on top, using "impact" (texture file already included in addon files)

The proc would light up the Soul Fire buttons

Questions:

• see if it makes sense to display a Spell Alert
  • below 35% hp, Decimation buffs Soul Fire, which itself proc Decimation
  • basically we end up in a loop of perpetual cast of Soul Fire
  • is it really worth a Spell Alert in this case?
• see if it interferes with other textures displayed on top, namely Molten Core and Backlash
  • top texture of Molten Core is disposable, if needed
  • top texture of Backlash is non-negotiable because it is an official Spell Alert from Retail

Implemented in #68
