- #showtooltip Death and Decay: This shows the tooltip for Death and Decay, which is a key AoE ability for Blood Death Knights.

- /cast [mod:alt] Death Grip; Death and Decay: With the alt key pressed, it casts Death Grip to pull enemies towards you. Without alt, it casts Death and Decay, placing an AoE damage field.

- /use [nochanneling] 13: This uses your first trinket (slot 13) if you're not channeling a spell, ensuring you don't interrupt important casts.

- /use [nochanneling] 14: Similar to above, this uses your second trinket (slot 14).

- /stopcasting: Stops any current spell casting to ensure the next ability can be cast immediately.

- /cast [combat] Vampiric Blood: In combat, this casts Vampiric Blood, which increases your health and healing received, crucial for survivability in tough content.

When to use this macro: Use this macro during PvE encounters where you need to maximize your AoE damage, control enemy positioning, and boost your survivability. It's particularly useful in situations where you need to quickly react to mechanics or manage your cooldowns effectively.

Customization Tips: You might want to adjust the trinket slots if you prefer different items or add conditions like [spec:1] if you want it to only work in your Blood spec. If you want to add more abilities or change the conditions, let me know.
