If it has stats... (Challenge to the playground)

[Inevitability]

Dire_Stirge: Your wizard becomes hostile and tries to kill the druid, then (if he survives) the druid takes (ability loss)/(damage).

Okay... This is about plan B, right? How about plan C (the one involving pulling a Sphere of Annihilation out of thin air)?

Rework of plan B (should've used a candle from the start):

Spoiler: Plan B.2

Show

Round 1: Use a Candle of Invocation to summon an Efreeti.
Round 2: Have the aforementioned Efreeti send you to a place exactly 5 feet from the creature's location. Ready an action to Planar Bubble.
Round 3: FEELZ MAH PLANAR BUBBLE!
Round 4: ???
Round 5: Profit!

And, in case you missed it, plan C:

Hm... Plan C, just in case the other plan doesn't work. This involves a 20th-level gray elf wizard with 25 Intelligence (18 base, +2 racial, +5 ability score increases).

Spoiler: Plan C

Show

Round 1: Chandle of Invocation for an Efreeti.
Round 2: Have one Wish cast upon yourself for a +5 bonus to intelligence.
Round 3: Have the Efreeti Wish you to the creature's location.
Round 4: Will a Sphere of Annihilation out of your Spell Component Pouch.

Spoiler: WTH?

Show

I know what everyone's thinking. However, look at this:

A spellcaster with a spell component pouch is assumed to have all the material components and focuses needed for spellcasting, except for those components that have a specific cost, divine focuses, and focuses that wouldn’t fit in a pouch.

And at this:

Material Component: An artifact, usually one of good perverted to this corrupt use.

A Sphere of Annihilation is an artifact. It also has no specific cost, fits in a pouch, and is not a divine focus. Therefore, it must be in your spell component pouch.

Round 5: Will the SoA towards the creature. Win.
